Deisgned from the ground up to be the heart of any mid-size RV, campervan, or marine power system. This unit combines solar, DC, (vehicle) alternator and standard AC power to efficiently manage all incoming and outgoing power in one unit!

Retro fit electrical systems that are added to by multiple users can often result in complicated wiring that requires physical unplugging when certain appliances are being run or if you are switching from solar panels on the roof to AC power in a camp site.

This unit combines all available power sources, and the vehicle batteries, to the total power load. The large (removable) LCD screen will provide real time data on all important power metrics allowing for quick glance at battery charge states and active power consumption.

Connect solar panels, vehicle alternator, starting battery to the input. Then connect deep cycle house batteries and all your vehicles appliances and DC power loads to the output. The system will find the best efficient means to manage all power and batteries in your electrical system. When parked at home (or at a camp site) with AC power, the unit will use AC to recharge and keep batteries at optimum level. No need to unplug or manually switch between devices.

The LCD screen can be removed and positioned in a remote location with the included extension cable. Allowing for the meter to be positioned in a convenient place to show all battery data. Leaving the bulkier main body to be installed in cabinets or under flooring with house batteries and or the rest of the electrical system.

Simplify your electrical system and maximise all available energy sources with this all in one complete power management system!
