VEVOR 4800W 48V Complete Solar Power Kit, 12*400W Monocrystalline Solar Panels + 51.2V 300Ah LiFePO₄ Battery + 48V 10KW Hybrid Inverter, Super High Output Off-Grid Solar Kit for Large House Shed Farm

Regarding your inquiry about the 4800W solar kit: Connection: This is an off-grid system. It is designed to power your loads directly and cannot be connected to your main panel box (grid-tied) as it lacks the required grid-synchronization/anti-islanding features for utility interconnections. Excess Power: As this is an off-grid system, it does not send excess power back to the grid/transmission lines. It is designed to store excess energy in the included LiFePO4 battery bank for your own use.

A single solar panel is 400W, 12 * 400 = 4.8kW, and the voltage of a single panel is 63V. The 12 panels are arranged in 6 series and 2 parallel configurations, with a total voltage of 63 * 6 = 378V. This inverter/controller unit has dual MPPT inputs, both with a maximum power of 500VDC and 5500W, totaling 1000VDC and 11000W. After inversion, the voltage is 120V.

This product has an output voltage of 230V, which is compatible with appliances operating at 220-240V. You can adjust the output to 120V or 230V according to the instruction manual, but it cannot output simultaneously. You can choose either single-phase mode (120V) or split-phase mode (240V).

We do not sell batteries separately; you may purchase 51.2V*300Ah batteries from other platforms.

Yes, you can connect multiple kits together to achieve higher output.
