Thursday - After watching a YouTube video last night where some friends upgraded the electrical system in their RV and while on their shakedown trip,they discovered that their house batteries weren’t being charged from their generator, I figured that I should test try this out.
I started the generator on the class C and turned on the Multiplus (inverter/charger). From the screen shot, you can see the generator was putting out 868watts and 54.3amps were charging the house battery (SOK LiFePO4). The AC out was the converter which was charging the original AGM house battery.
There was 5.02amps going into the AGM battery which is around 68 watts. A few minutes later, it jumped up to around 15amps. I turned off the generator after around 5 minutes of run time.
One surprise to me was that the Multiplus needs to be running to allow any AC power into the RV. Not really an issue as it will probably be running all the time while the RV is being used.
This is the SmartShunt showing the battery voltage and current. The AGM battery voltage is shown at the bottom labeled as “Starter battery”. As I mentioned before, the AGM battery is used to start and run the generator only.
