MUST 5.5kW / 5.5kVA 48V Pure Sine Wave Hybrid Inverter (100A MPPT)
MUST 5.5kW / 5.5kVA 48V Pure Sine Wave Hybrid Inverter (100A MPPT)
Overview
Power your home or small business through grid instability and load shedding with the MUST 5.5kW 48V Pure Sine Wave Hybrid Inverter. Engineered to deliver reliable, uninterrupted power, this multi-function inverter intelligently coordinates energy inputs from solar PV panels, 48V battery storage, and the utility grid to ensure continuous operation for essential appliances and sensitive electronics.
Equipped with a high-capacity 100A MPPT solar charge controller, the unit accommodates solar arrays up to 6,000W with high-voltage input capability (500V DC max), maximizing PV collection even in overcast weather. Featuring wide compatibility with both LiFePO4 lithium-ion and lead-acid battery banks, a multifunction LCD display, and optional remote Wi-Fi monitoring, the MUST 5.5kW provides a versatile, cost-effective foundation for backup and off-grid solar energy systems.
