I have a multiplus compact 12/2000 and I have just wired everything. First time wiring a solar project for our RV. I have the MPPT solar charger 2 100Ah battle born lithium batteries. My problem is that I have wired a 15 amp breaker on my ac out to my outlets in my RV. I have 111-116 volts coming out of the inverter depending on if it is hooked up to shore power or running off the batteries. Whenever I turn the breaker on for the outlets the inverter clicks and the inverter light cuts out and alarm light stays on solid and power is cut off and the fans kick on. Everything else seems to be working properly and this only cuts out when I turn breaker on for the outlets. I do not have a ground wire from my ground bus on the 30 amp load center that the 15 amp breaker is in. All ground wires from outlets and inverter connect to this ground bus but I do not have a ground running from that bus to shunt bar for batteries. I do not know why the inverter would be clicking and shutting off and fans turn on. Am I missing something here???
Thanks.
