Product Information

The Sterling Pro-S Combi 12V 3500W is a pure sine wave combined inverter and charger. It runs from a 12V DC battery bank to give a 230V AC sine wave output (50Hz) for equipment that needs a power source similar to a household supply, up to its rated continuous load. It has a 4-step digital progressive battery charger, and its AC input is 230V 50Hz.

A 30A automatic crossover switch runs your appliances from shore power when it is connected; when shore power is disconnected, the switch moves over to take current from the batteries, with a switching time of 20ms. In inverter mode an earth-neutral bonding link allows RCD breakers to work. The remote control panel and cable are included.

Key Features

Pure sine wave inverter: 12V DC in, 230V AC out at 50Hz
4-step digital progressive charger with automatic charge characteristic
For FLA, SLA, AGM, GEL and LiFePO4 batteries
30A automatic crossover switch with a 20ms switching time
Charger-only setting, so the inverter does not engage if shore power fails
Earth-neutral bonding link in inverter mode, so RCD breakers can work
Remote control panel and cable included: switches the unit on and off and selects power saver mode
Hard-wired AC connection and M8 stud DC connection

Suitability

For 12V systems that need 230V AC for equipment that requires a power source similar to a household supply, up to the rated continuous load. Recommended battery capacity: 500 - 1100 Ah. The AC side is hard wired. Do not open the unit: high internal voltage.
