Four Essential Functions in One Unit

Inverter

Produces clean 230V pure sine wave power from a 48V auxiliary battery bank, making it suitable for sensitive electronics as well as demanding household appliances.

AC Battery Charger

Automatically recharges the auxiliary battery when shore power or a generator is connected, with charging current of up to 75A.

MPPT Solar Charger

Connect up to 1800W of solar panels directly to the PG4.0S. The integrated MPPT controller efficiently converts available solar energy into battery charging power.

Bidirectional DC-DC Charger

Charges the 48V auxiliary battery from the vehicle alternator while driving. When the engine is switched off, stored energy can also be used to help maintain the starter battery.

Built for Safe Mobile Power

The PG4.0S includes an insulation-monitoring system designed to detect electrical leakage and shut down the inverter when required. A 32A/30mA RCD safety device and fast transfer function further support a safe and dependable mobile-power installation.

Recommended Applications

• Motorhomes and campervans

• Caravans

• Boats and marine applications

• Service and utility vehicles

• Mobile workshops

• Emergency and specialist vehicles

• Mobile catering vehicles

Installation Note

The PG4.0S is intended for indoor installation in a dry, suitably ventilated location. Battery compatibility, solar configuration, alternator connection, cable sizing and electrical protection must be confirmed before installation. Installation should be completed by a suitably qualified professional.
