Applications

Off-Grid Solar Systems

Combine compatible solar panels and a 48V battery system to supply loads within the inverter's continuous output and starting-load limits.

Backup Power for Selected Loads

Pair the inverter with a compatible external battery to support selected loads during AC supply interruptions. Runtime depends on battery energy and load consumption.

Select the Right Configuration

Choose the inverter according to continuous load power and equipment starting requirements. Then confirm the external battery's operating voltage, current capability, charging settings and communication compatibility.

PV array design must match the supplied inverter's voltage and current limits, including solar module open-circuit voltage at the lowest expected temperature.

Frequently Asked Questions

Does this product include a battery?

This is an inverter with integrated solar and AC charging functions. It is not an all-in-one battery storage cabinet. Confirm any external battery supplied with your order separately.

What is the difference between the three models?

FH-5000 provides 5kW rated output, FH-5500 provides 5.5kW, and FH-6200 provides 6.2kW. Their maximum PV input powers are 5kW, 5.5kW and 6.5kW respectively. Maximum PV input current and charging current also vary by model.

Can multiple inverters operate in parallel?

The datasheet lists no parallel capability for this series. Do not connect inverter outputs in parallel.

Can it operate without a battery?

Battery-free operation is listed as a product function. Confirm the supported PV/AC operating conditions and load requirements for the supplied configuration.

Is this a grid-export inverter?

This series is specified as an off-grid inverter. Its AC input supports supply and charging functions; grid-export capability is not specified.
