48V All-in-One Energy Storage System · Inverter + Battery + Controller
The All-in-One ESS combines a hybrid inverter, LiFePO₄ battery, and dual MPPT charge controller into a single compact unit — 6,500W continuous output with 8,000W of PV input capacity, built for homes and businesses that want full off-grid capability without a rack of separate components.
Most off-grid systems require separate hardware for solar charging, battery storage, and inverting — each with its own wiring, mounting, and maintenance. The All-in-One ESS folds all three into a single cabinet: a hybrid inverter, a 5,120Wh LiFePO₄ battery, and dual MPPT charge controllers, pre-integrated and ready to connect.
That compact footprint makes it a strong fit for installations with limited space or where a more discreet setup matters, and it's generally easier to install and maintain than a system built from separate rack-mounted components.
6,500W rated output, converting solar and battery DC power into clean 120VAC for your home or business appliances.
51.2V, 100Ah, 5,120Wh of integrated storage for power when the sun isn't shining.
Two MPPT trackers manage up to 8,000W of solar input and up to 120A of charging current.

A hybrid inverter, an integrated LiFePO₄ battery, and dual MPPT solar charge controllers — everything needed for off-grid power generation and storage in one unit, rather than separate boxes to mount and wire together.
Yes — Rich Solar offers a battery-only purchase option (51.2V 100Ah) for those who already have inverter and charge controller hardware, or who want to expand an existing All-in-One system's storage.
Yes — it accepts AC input from either utility power or a generator, with programmable priority for whether it draws first from solar, battery, or grid.
Through the companion mobile app on iOS or Android, or via USB, RS232, SNMP, Modbus, GPRS, or WiFi for system integration.
Yes — the system supports scalable Li-Ion battery expansion beyond the integrated 5,120Wh unit.
Given the voltages, currents, and grid/generator interconnection involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
