The inverter's built-in MPPT accepts up to 4400W of solar at up to 150V, while its 40A AC charger tops up from the grid. Transfer between bypass and inverter typically takes 10 ms, keeping essential home circuits running through outages. Self-heating batteries keep charging reliable in cold weather, and parallel expansion up to 8 batteries lets the system grow.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003caside style=\"background:rgba(255,255,255,0.07);
