☀️ For home solar & battery owners

Your solar system,
at a glance.

SolarCompanion turns your inverter data into a live view of your home — what the panels make, what the house uses, and how long the battery will last when the grid goes down.

Everything your inverter knows, made simple

No more digging through portals. Open the app — or just glance at your home screen.

Live energy flow

An animated view of your house shows power moving between solar, battery, home and grid — with local weather and day/night built in.

Home screen widgets

Battery level, solar output and grid status right on your home screen, refreshed in the background so it's ready whenever you look.

Battery time left

When the grid goes down, see roughly how long your battery will last — learned from your own usage and solar pattern, not a guess.

Outage & low-battery alerts

Get notified the moment the grid drops or comes back, when the battery runs low, or when usage spikes during an outage. On iPhone, a Live Activity keeps the countdown on your Lock Screen and Dynamic Island.

Multiple sites, multiple brands

Watch your home, the shop and your parents' place from one app. Connect Growatt and Deye systems side by side, in English, Bahasa Melayu, ไทย, 中文 or မြန်မာ.
