AC power loss on Shore panel 1

[Patuxent Bob]

My R43 no longer has Shore power on the Shore panel 1 electrical panel. There is power on Shore panel 2.
The Inverter shows a status light of amber. There is an inverter message of EO1, which is that the house battery is low on charge. The charger has been running and the panel reading for the house battery is 100% charged.
When I try to test an outlet using the house battery power via the inverter, I will get power for 2-5 seconds and then the power shuts off.

When the inverter is turned off at either the inverter control panel or the inverter control switch, there is no difference. There is no AC shore power, even with the inverter off.

Is there a fuse or breaker for that side of the panel? If so, where should I look? What other considerations are there?
Thanks,
Bob

Hello Bob,

A few questions first:

• Is the inverter switch on the 120V AC panel turned on?
• Is the switch in the starboard cockpit locker by the inverter turned on?
• I would also check the connections at the inverter.

If the inverter is on, the left-hand side of the panel will be powered by the inverter, which converts 12V DC from the house battery to 120V AC to supply those breakers. While converting, the controller will display an orange light.

If you turn on the Inverter Bypass breaker at the top left corner of the panel, this allows shore power to pass through the inverter and supply all inverter-powered breakers without converting 12V DC from the batteries. In this mode, the controller will display a green light. The green light may blink briefly while the system determines whether the incoming power is suitable to transfer.

Here is how the power coming in works on your boat: Dock Outlet > Shore Cabel > Shore Inlet > ELCI on 120v Panel > Main Breaker to the left of the ELCI > Line 1 (Inverter Bypass Breaker**, Washer, and Dryer Breakers) and Line 2 (All of the breakers on the right side of the panel)

Please let me know if this helps and what you find.

Hello Jared,
Answers:
1.The inverter switch on the 120V AC panel is on.
2. The rotary inverter switch in the small cockpit locker is in the on position.
3. The connections on the right (aft) side of the inverter are tight and clean. If there are connections on the left or forward side of the inverter, I am not able to see or access any connections.

When the inverter power button on the remote display panel is pushed to turn on the inverter, the status light shows amber/orange rather than green. There is a message r10. I don't know what that means.

The inverter has worked flawlessly for 5 months by having been in the "on" position. There were two West Marine space heaters on board to maintain interior temp above freezing. One heater was connected to a galley outlet and the other to a fwd stateroom outlet. Both of those circuits have breakers on the left side of the AC panel. (These heaters ran without incident last winter and from November until just recently. I check the boat daily (until a reecent snow/ice storm that prevented access to the boat.)

What would be the next logical steps?
Thanks for your attention,
Bob
