Seem to have lost power to the inverter. the breaker marked for inverter is on

First, I'm not a Coachmen RV Tech. (but most DC to AC inverters are not brand specific.)
* Check inverter fuse (on actual inverter frame). Replace.
* Check DC voltage at inverter. Should be 12 (or 24 VDC) depending on your system battery supply and inverter.
* Check the DC cable connections; crusty, dirty? Cut all power. Remove and clean terminals. Re-connect and check.
* DC okay? Check 110 VAC power at output of inverter. No power? Replace inverter. (possible power spike damaged it or it over heated)
* 110 VAC okay? Check the power panel breakers. If stuck in middle then turn all the way off to reset and turn all the way back on to activate. Check AC power at outlet(s)
* Still no power (at outlet)? Check all outlets. If some still works then there is a problem with the power (wires) distribution. You will need an electrician to trace the wires back to the break in circuit.
* Be safe. check your warranty and call for service.
* Note; your inverter may be on a separate warranty.
Aloha, ukeboy57

it seem you need fuse and stater.

All of the windows get power from a 30amp breaker marked number one.

Are you wanting to install circuit breakers on the DC (battery) side? If so, you won't need them to protect the unit as it is already fused. But, it would be a good idea to install them as close to the battery so that if a wiring fault develops in te cable going to the inverter, it would be protected as well.

For the AC side, breakers are sized according to the wire size, not the capacity of the inverter. But, you can always use a smaller size if you want to try and protect the inverter from overloads as well. Your inverter is rated at 1000 watts, which is a bit over 8 amps of AC current. Use a 10 amp circuit breaker, and don't use smaller than 16ga wire for short distances. Use larger guage wire (12ga is 20amp residential requirement, 14ga is 15amp residential requirement) for the longer runs.

This inverter is not designed for a permanent install, its not intended to be run continuously. There are inverters designed for this, you can find an idea of product selection at rv suppliers, alternative energy shops, etc.

check the system but you may have to turn off the batteries
the inverter is charging the batteries but when mains power fails , the batteries will be discharging back through the inverter that is dc converted back to ac
if you power on a genset and the ac is not phased correctly, what you describe will happen--- inverter ac from the batteries against genset ac to the inverter-
If you had mains power on then it would dead stop the genset because of the out of phase situation
it all has to do with the 2 wave patterns for ac current from each unit being in harmony and not working against each other

It appears that you have lost one half of your power. That is you no longer have 220 volts but do have 110, enouch to power the electronic ignition. I would check the circuit breaker first to see if it is sending power on both hot wires or just one.

Inverters normaly have inbuilt protection built into them check for reset button/switch.

First problem is caused by the new generator producing too high a frequency... 65 Hertz is above the inverter limit. Adjust the governor down to 60 or 61 Hertz.
Breaker tripping may be due to excessive current draw from the Honda. Check the max AC input menu on the inverter. It might have been set lower to avoid overloading the original generator but if DC power was turned off at any time while you were changing generators, the inverter would have returned to it's default settings which may exceed the Honda's capacity.

Try disconnecting the DC input for 5 min. or so, this will generally reset the unit.
