An XDA writer this spring described ripping out a shelf of small UPS units and dropping in one whole-house battery instead. Fewer beeping bricks, one dashboard, and every circuit in the panel gets the ride-through. The catch is that the dashboard now matters more than the hardware. If you cannot see state of charge, solar production, and reserve percentage from your phone, you will not trust the system when a summer storm rolls in. We spent a week with the best apps for home battery monitoring on Android, testing seven owner apps that ship with the most common whole-home battery and solar-plus-battery brands. The list assumes you (or your installer) already picked a hardware family and need to know what the daily companion app is like.
What to look for in a home battery monitoring app
Home battery apps split into two camps: brand apps that ship with the hardware and third-party monitors that overlay the whole panel. Both have a place. Before picking one, work through these criteria.
- Real-time draw and charge, not five-minute averages. During an outage you need to know if the fridge kicked on in the last few seconds, not what the average was.
- Reserve percentage control from the phone. Storm coming through tonight? You want to top the battery to 100 percent from bed, not from a browser tab on a laptop.
- Per-circuit or per-device visibility. Whole-home kilowatt-hours are a starting point. Knowing which circuit drained the reserve at 3 a.m. is what changes behavior.
- Local fallback when the cloud is down. Tesla’s app talks to the Gateway on your LAN when the internet drops. Most brand apps do not.
- Alerts you can trust. Grid outage notifications, low-reserve warnings, and firmware update prompts belong in push, not buried in a web portal.
- Historical export. CSV or API access matters if you want to feed the data into Home Assistant, a spreadsheet, or a solar performance report for a rebate.

#1. Sense Home, best for a cross-brand overlay on Powerwall or Enphase
Sense Home clamps onto the mains in the panel and uses machine learning to disaggregate loads, then pulls in Powerwall or Enphase battery data through the integrations menu. On a house with a Powerwall, the dashboard shows solar production, battery state of charge, grid export, and the individual devices Sense has learned, all on one screen. During an outage, Sense keeps working because the monitor is inside the panel and the Powerwall keeps the Wi-Fi router alive. The device disaggregation is the reason to buy it: after a few weeks it starts naming your fridge, well pump, and heat-pump water heater by itself.
Where it falls short: the hardware runs about $349 and needs an electrician to install the clamps. Device detection is patient work, some loads it never nails, and the accuracy for very small always-on devices below 20 watts is uneven.
Pricing:
- Free: full app access once the hardware is installed. No subscription.
- Paid: no software tier. One-time hardware cost.
Download: Google Play
Bottom line: buy this if you own a Powerwall or Enphase system and want one dashboard that shows the whole panel plus the battery, not two apps side by side.
#2. Tesla, best for Powerwall 2 and Powerwall 3 owners
The Tesla app is the daily driver for any Powerwall household. The energy screen shows a live flow diagram between solar, home, Powerwall, and grid, with historical views for the day, week, month, and year. Backup Reserve lives on the main screen so raising it before a storm takes two taps. During an outage the app keeps working over the local network because the Gateway serves the same data locally, one of the few brand apps that does this properly.
Where it falls short: you cannot see per-circuit consumption unless you have a Tesla Backup Gateway 2 with expanded metering, and even then the granularity is limited. Historical data export is basic, and the app buries useful things (Storm Watch history, sub-hourly graphs) two or three menus deep.
Pricing:
- Free: full monitoring and control for owned Powerwall systems.
- Paid: no premium tier for energy features.
Download: Google Play
Bottom line: the only Powerwall app worth using. Local fallback and the two-tap reserve control are what make it work when the grid is down.
#3. Enphase Enlighten, best for IQ Battery plus IQ microinverter systems
Enphase Enlighten (marketed as the Enphase App on the store page) is the companion for IQ Battery 5P, IQ Battery 10, and any home with IQ microinverters. The dashboard reports per-panel production down to the module, battery state of charge, charge and discharge energy, and Storm Guard status. The Battery Profile screen lets you shift the balance between backup reserve, self-consumption, and grid export without calling the installer. The panel-level view is the killer feature: if one microinverter drops offline, you see it that day.
Where it falls short: the free tier updates roughly every 15 minutes for consumption data (real-time is on the production side), which trails Tesla and Sense noticeably. Historical drill-down beyond a rolling window is gated behind the Manager tier.
Pricing:
- Free: production, consumption, battery state, and profile control. Rolling historical window.
- Paid: Enlighten Manager for deeper historical analysis, priced at $9.99 per month or a one-time $249 lifetime purchase.
Download: Google Play
Bottom line: the app to keep on the home screen if you have IQ Batteries and Enphase microinverters. Layer Sense on top if you want real-time consumption disaggregation.
#4. mySolarEdge, best for SolarEdge inverter and Home Battery owners
mySolarEdge covers homes on SolarEdge HD-Wave or Energy Hub inverters, and it is the only app that lets battery owners change their own settings, including Weather Guard, which automatically tops the battery to full when severe weather is forecast within a few hours. The app shows real-time production and consumption, per-string data, EV charger control if a SolarEdge charger is installed, and a critical-loads toggle. Battery mode switching between Backup Only, Time of Use, and Maximize Self-Consumption is on the main screen.
Where it falls short: the app is only useful with SolarEdge hardware; there is no third-party integration. Consumption metering requires a SolarEdge Modbus meter installed in the panel, which not every install includes. The Android version has had layout bugs after larger firmware updates, though the June 2026 release cleaned most of them up.
Pricing:
- Free: monitoring, battery settings, EV charger control, Weather Guard.
- Paid: no consumer subscription tier.
Download: Google Play
Bottom line: the correct app for SolarEdge homeowners, especially since Weather Guard is not available anywhere else in the SolarEdge ecosystem.
#5. EcoFlow, best for DELTA Pro Ultra and PowerOcean home backup
The EcoFlow app is the same binary that manages a $500 river-boat power station and a whole-home PowerOcean install, which is either a strength or a distraction depending on your point of view. For DELTA Pro Ultra and PowerOcean owners, the dashboard shows total input in watts (solar plus AC combined), output by category, battery state of charge, estimated runtime, and charge or discharge schedules. Smart Home Panel 2 users get twelve independently controllable circuits, so you can shed non-critical loads during an outage without going down to the panel. The app talks to the hardware over Bluetooth when you are on the same premises and Wi-Fi from anywhere.
Where it falls short: the interface swings between prosumer and camping-gear tones because it serves both audiences. Notifications are chatty by default and worth pruning. The PowerOcean feature set on the app has trailed the marketing copy on the box, though 2026 updates closed most of the gaps.
Pricing:
- Free: full control and monitoring for all EcoFlow devices on one account.
- Paid: no consumer subscription.
Download: Google Play
Bottom line: the app to have if your backup is EcoFlow, and one of the better companion apps for anyone who wants to control panel-level loads during an outage.
#6. Bluetti, best for EP600 and EP900 modular home systems
The Bluetti app (developer name PowerOak) manages Bluetti’s home ESS lineup, including the EP600 and EP900 with B500 expansion batteries. The dashboard shows solar input, grid import and export, battery percentage, and the current working mode (self-consumption, backup, or time of use). Charge and discharge scheduling is per-day with time blocks, useful if you are on a time-of-use rate plan and want to shift the discharge window to peak pricing. Firmware updates run from the app itself.
Where it falls short: the Android build has been slower to receive polish than the iOS one, and the translation from the original Chinese-language UI is uneven in places. Cloud dependency is heavier than Tesla’s; a home internet outage takes the app offline for anything beyond Bluetooth-range control.
Pricing:
- Free: monitoring, scheduling, mode switching, firmware updates.
- Paid: no subscription for owners.
Download: Google Play
Bottom line: the right app for Bluetti hardware, and better than it was two years ago, but pair it with a UPS on the router if you want any control during an internet outage.
#7. Generac PWRview, best for PWRcell and PWRview ATS households
Generac PWRview connects to PWRcell battery systems, PWRview home energy monitors, and Generac standby generators with a PWRview ATS. The main screen shows live consumption, solar production, PWRcell state of charge, and forecasted monthly cost against the utility bill. Mode switching between Self-Supply, Clean Backup, and Priority Backup is one screen deep. For homes that pair a whole-house battery with a Generac gas standby generator (a common belt-and-braces setup in storm-heavy regions), this app is the only place you see both at once.
Where it falls short: the app is inherited from the Neurio acquisition and still shows its age in places, especially on tablets. Notifications for grid events lag Tesla and Enphase by a noticeable margin. The Play Store rating is lower than the app deserves because installer commissioning issues get filed against the app.
Pricing:
- Free: monitoring, mode switching, bill forecasting.
- Paid: no consumer subscription.
Download: Google Play
Bottom line: required for PWRcell owners; genuinely useful for anyone running a PWRcell alongside a Generac standby generator.
How to pick the right one
- If you already own a Powerwall: install the Tesla app. It has local network fallback, which matters more than any feature on any other app in this list.
- If you already own an Enphase system: install Enphase Enlighten and consider Sense Home as an overlay if you want real-time consumption.
- If you already own SolarEdge inverters plus a SolarEdge Home Battery: mySolarEdge, because Weather Guard is not available anywhere else.
- If you own an EcoFlow DELTA Pro Ultra or PowerOcean: the EcoFlow app. Turn off half the default notifications the first day.
- If you own Bluetti EP600 or EP900: the Bluetti app, plus a small UPS on your router so you can still read the dashboard when the internet is down.
- If you own Generac PWRcell: PWRview, especially if you also have a Generac standby generator.
- If you have not picked hardware yet and want one dashboard for whatever you buy: install Sense Home first, then choose a battery brand whose app plays nicely with it (currently Powerwall and Enphase are the smoothest integrations).
FAQ
What is the best free app for home battery monitoring?
Every brand app for home batteries is free with the hardware. If you want a cross-brand dashboard, Sense Home is the closest option, but it requires the Sense monitor in your panel. There is no useful third-party home battery monitoring app that works without hardware you have already bought.
Can I monitor a Tesla Powerwall from Android without an internet connection?
Yes. The Tesla app connects to the Powerwall Gateway over the same Wi-Fi network when the internet is down, so state of charge, backup reserve, and live flow keep updating. Enphase, SolarEdge, EcoFlow, Bluetti, and Generac all require a cloud round trip and go dark during an internet outage.
Does the Enphase app work with Tesla Powerwall?
No. Enphase Enlighten only shows Enphase hardware, and the Tesla app only shows Tesla hardware. To see both in one place, use Sense Home with both the Enphase Envoy integration and Powerwall integration enabled, or use Home Assistant with the community Powerwall and Enphase integrations.
Do I need a subscription to use these apps?
Not for the essentials. All seven apps offer real-time monitoring, mode switching, and reserve control for free. Enphase is the only one with a paid tier (Enlighten Manager, $9.99 per month or $249 lifetime) that adds deeper historical analysis. Everything you need day to day is on the free tier.
Which app has the best per-circuit visibility?
For the panel itself, Sense Home has the best per-device disaggregation, and EcoFlow’s Smart Home Panel 2 gives you twelve directly-controlled circuits. Tesla’s app is weakest here: you get whole-home consumption, not per-circuit, unless you add expanded metering to the Gateway.
Can these apps replace a UPS for the office equipment I still care about?
Only if the house battery is wired to back up the circuit those devices sit on. Whole-house batteries protect anything on the backed-up subpanel, but the transfer time (typically 20 to 40 milliseconds for Powerwall, EcoFlow, and Bluetti) is fast enough that most desktops and NAS units stay up. If a device is fussy about brownouts, keep a small UPS in line as a second layer.
