Inverter Charger Installation Guide
Description
The Mastervolt Mass Combi Pro combines a powerful 3 step battery charger along with a heavy duty true sine wave power inverter to provide AC output to operate household items. The unit can be connected up to shore power or a generator for charging and the AC output will automatically switch between mains and inverter mode. It has two separate AC outputs, allowing critical equipment to be put on a different circuit to other appliances to protect them from heavy loads. The inverter/charger is built to be reliable and user friendly, and is equipped with MasterBus Combi integration for easy operation along with the rest of your Mastervolt system.
The Mass Combi Pro features the Power Assist function, which prevents main fuses or breakers being tripped in the event of a weak power supply. It also eliminates power failures and dips to maintain reliable performance. The unit is equally capable at handling heavy loads and more sensitive loads, and with a true sine wave output will not cause harm or damage to your appliances. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming.
This model can be used in a 3 phase system, or you can combine up to 10 units in parallel for higher power outputs.
