Description
Mastervolt MASS COMBI ULTRA 48/3500-50 Inverter/Charger - 38343500
Part No: 38343500
The Mastervolt Mass Combi Ultra combines a 3 step battery charger, able to charge a second 12v or 24v battery simultaneously, along with a heavy duty true sine wave power inverter. The unit has two AC inputs and can be connected up to shore power and generators 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 Ultra 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 unit can provide up to 50% of charging current or inverter capacity without using any fan cooling, and so runs very quietly. Even when operating at maximum capacity, or performing in high ambient temperatures, the fan speed is regulated to only run in a linear way, meaning it wont spin too fast or make unnecessary noises. This model can be used in a 3 phase system, or you can combine up to 10 units in parallel for higher power outputs.
