    AiLi Battery Shunt

    My AiLi battery shunt works great, until, I turn on my inverter. When I switch on my inverter, the shunt will measure the power usage, however, it deletes the battery power % and Amp hrs information. Has anyone else had this issue? More importantly is there a fix? Thanks

    Grounding my van electrical.

    The electrical components of my system are run to positive and negative bus bars. Question: Can I ground the whole system by running a grounding wire from my negative bus bar to a chassis ground? If I do this, do I need to still run separate grounding wires from my solar charge controller...

    Fuse between power converter and battery?

    I have a 45amp lithium power converter. I had read somewhere that the wire from this power converter to the batteries does not require a fuse, because the line is already protected by fuse fuse on the 120v side. However, I have looked at some schematics that show a fuse. Thanks.

    Solar Charge controller, how many amps?

    I want to install 600 watts of solar on my van. After performing a basic calculation of 600/12 = 50, it seems that I would need at a minimum a 50 amp charge controller. I am a little confused as I am looking at starter kits from Grape solar and Rich solar 3 X 200-watt panels with only 40 amp...
