Power Upgrade with Enerdrive

Power Upgrade with Enerdrive

Many motorhomes are imported from countries that don’t spend as much time as Kiwis do off grid… and solar definitely plays a large role when doing a power upgrade as sunshine is free!

Make the most of all your power sources

Work out how you are going to use your motorhome, what real estate you have available and the amp hour capacity you want.  Trying to get to 20% is ideal but probably not achievable due to limited roof space.  100W of solar will yield between 5 & 6 amps.

A Battery Charger uses mains power (230v AC) to charge your house battery/batteries. The Enerdrive battery chargers are available in 20/40/60A to suit battery capacity (20% is a good guide so if you have 200Ah of battery capacity then a 40A charger is appropriate).  They are also Lithium ready.

A DC/DC unit is a dual purpose unit is designed to take charge from the engine alternator to the house batteries.  To reduce emissions modern vehicles have alternators that are engine computer controlled, the Enerdrive DC/DC charger will transfer charge, even with the motor at idle. The other task the DC/DC charger can perform is regulating the solar charge.  If your power upgrade involves extra solar then the DC/DC charger is a convenient way of replacing the existing, no longer serviceable, solar regulator and saving valuable space. The Enerdrive DC/DC charger is capable of 40 amps.

An Inverter is a device that takes DC current (from the house battery) and basically switches back and forth to create AC current (230v) to power appliances in your motorhome.  It is the only way (other than a generator) of producing 230v power when you are off grid.  

An inverter is a high DC consumer, so people generally avoid using this method to run their water heaters, fridges, air conditioning units and chargers. Inverters come in various sizes.  The Enerdrive inverters are suitable for charging laptops in 500W, 1000W for E- bike batteries or to run sleep apnea machines, and 2000 & 2600W that are suitable for microwaves and coffee machines.  The 2000 and 2600W inverters are available with a built in auto transfer switch that when wired into the motorhomes 230v circuit enables all wall sockets to be either mains or inverter fed. The inverter will automatically divert to house battery when mains power is not present, conversely when using house battery, if the mains were to be connected to the motorhome the inverter would switch over to that source essentially allowing the 230V to pass through it to the sockets.
