NFA GLOBAL / ENERGY FOR YOUR EVERYDAY
Power equipment directly, or store solar for your home. Meet 8655 and 8657: different connections, different jobs, one clear place to compare.
OFF-GRID POWERA LiFePO₄ off-grid unit with solar input, for compatible loads connected to the unit itself—not a grid-feed system.
GRID-CONNECTED STORAGEFour MPPT inputs and a master-and-expansion architecture, for planning a solar system that keeps daytime surplus for later.
Original manufacturer renders and supplier-listed specifications. Illustrated combinations do not define the final supplied kit.
THE DIFFERENCE THAT MATTERS
Battery size alone won’t tell you which system fits. Start with how the energy reaches the things you want to power.

| How is it structured? | Standalone off-grid unit | Master with separate expansion batteries |
| What should I check first? | Loads, startup demand and voltage | Surplus, inverter and grid connection |
