I have an EasySolar 5000VA (=MultiPlus) connected to a 48V Lifepo4 battery. I was wondering, where or how I could connect a 48V to 24V DC-DC converter.
The DC-DC converter is supposed to power a Teltonika RUT950 4G router (9-36V) which is connected to the GX computer and gives me remote control over the EasySolar, even if its inverter (MultiPlus) is turned off.
I know, that there are several relay's from the MultiPlus and one is there at the SmartSolar charge controller. That relay can be configured when to be switched, but there was no Voltage when I measured, no matter what settings... However, is this the way to go? The router drains max 7W of power... should not be a problem I guess...?
Or could I hook the router directly to a relay without a DC-DC converter?
Or has anybody an idea, how I would power the router the right way?
