3.6kW Solar Inverter for 24V Batteries with 100A PV and AC Charging

Flexible 24V Battery Integration for Solar Backup Systems

This 3.6kW solar inverter is designed around a 24V battery platform and supports compatible lithium and lead-acid batteries. It integrates photovoltaic charging, AC charging, pure sine wave output and battery monitoring in one unit.

The photovoltaic charger and AC charger are each rated for up to 100A, while the listed maximum combined charging current is 100A. Charging settings must therefore be configured according to battery capacity, chemistry, BMS limits and available source power.

This version is positioned for battery distributors, solar installers and system integrators that require a higher-output inverter for 24V battery systems, with multiple communication interfaces and optional WiFi monitoring.

Battery Charging and System Integration

Battery Capacity and Charging-Current Planning

The maximum charging current should not automatically be applied to every battery. Installers must follow the battery manufacturer’s permitted charge rate, BMS current limit, cable specification and protection requirements.

The specification lists a 27V floating-charge voltage and a 29.2V overcharge-protection voltage. The final settings should match the selected battery chemistry and supplier instructions.

The inverter provides 3.6kW of continuous pure sine wave output. Battery capacity determines backup duration, while the inverter rating determines the maximum combined load that can operate at one time.

Battery and Charging Specifications

24V Battery Solar Inverter FAQ

Does the inverter support both lithium and lead-acid batteries?

Yes. Both types are listed, but the charging voltage and current settings must match the selected battery.

Does 100A PV plus 100A AC equal 200A charging?

No. The specification lists a maximum combined charging current of 100A when photovoltaic and AC charging are used together.

Can every 24V battery accept 100A charging?

No. The permitted current depends on battery capacity, chemistry, BMS rating, cabling and protection equipment.

What communication interfaces are available?

The inverter includes LCD, RS485, RS232 and USB interfaces, while WiFi monitoring is listed as optional.

Can utility power recharge the battery when solar production is low?

Yes. The built-in AC charger can supplement photovoltaic charging according to the configured source and charge-current settings.
