No output power from inverter after solar install

Just installed 3 170 watt panels on 2018 hurricane and now TVs aren’t working or plugs, seems like there is no output power coming from inverter now, TVs also will not work with generator running but plugs are.. Any suggestions?

Sounds like a circuit breaker tripped. Check the panel for the entertainment breaker and flip it just to reset it.

Did you install the solar controller first and wire to the batteries with the correct polarity? Or did your Hurricane have pre-installed wiring for solar?

Make sure you never knocked a wire loose

it would not be the Inverter if these items also do not work on the generator - you have a tripped breaker.

check the main breaker, or the circuit breaker for the outlet(s)

check the breaker on the generator itself

check the breaker on the Inverter


now, you say you 'just' added solar panels. How did you wire them to the coach, and did you 'change' any existing wiring?

Reset all the breakers and still nothing, I have 2 inverters, one for fridge that is working fine, the other is for the TVs and outside kitchen, that’s the one that’s dead. 12 volts at inverter but no output power, there are 2 breakers in battery compartment for both inverters, tripped and reset those as well but still nothing.

Did not rewire for solar, coach came prewired for solar, lines terminated under the bed where the inverter is, added controller there and the guy who did solar ran lines from controller to inverter, he said it didn’t need to run to battery’s because inverter was hooked to batteries, seems to work because batteries are fully charged but do you think that wiring can be problem?

Yes, the solar controller should be hooked to the batteries, not to the inverter. The inverter has its own separate connection to the batteries.

I will disconnect everything and see if that fixes issue then figure out how to get from under bed to battery compartment to hook up controller to battery

solar is not run thru the inverter, but directly to battery bank - but, I can see how someone might ‘assume’ it’s ok to use the inverter’s charger connection, IF you have an integrated unit - though that is not the correct design, and may pose some problems...

if you have a simple inverter, then NO, solar to the inverter is not going to work, it could even cause the inverter to either ‘sense’ that it’s output is not needed, or continually trip it’s internal breaker...

Rookie question here, but would it matter if the solar charge controller is hooked up to the same terminals on the inverter that the batteries connect to?

I’m going to disconnect everything from the inverter, it was working fine before then as soon as he connected leads to inverter before he hooked into controller we lost power to TVs and outside fridge,

I know it's a simplifies diagram, but it led me to my previous question.

no, again, solar or solar controllers do NOT 'hook up' to any inverter...they hook to the BATTERY BANK only.

Found the problem, opened up junction box after inverter to find one of the white wires pulled out of wire nut, reconnected wire and everything is working now. When we moved inverter to install battery leads we must have pulled wire out. Left it installed the way we had it and it’s pulling in 13.4 amps from panels and batteries are full, called xantrex and were told as long as line from battery to inverter wasn’t more than 10 feet we can install this way. Seems to be working fine so I’ll leave it for now

That’s exactly what happened, junction box just past inverter, found 1 white wire pulled out of wire clamp, the wires were barely stripped back from manufacture so I stripped them back some more and put wire nut back on and back to normal. Thanks
