Get 30-40% more runtime from your existing inverter batteries
Northern and western India suffer daily evening power outages as solar generation drops while demand spikes, with insufficient thermal supply forcing reliance on expensive spot markets
BatteryMax uses your specific inverter and battery details plus evening outage predictions to give precise load management advice. The app tells farmers when to run pumps, households which lights and fans to keep on, and shops how to protect inventory — all without buying new hardware. It also tracks battery health over time using Indian climate data.
