Ranger Tug r-23 inverter Reset

I replaced the batteries on my 2020 Ranger Tug R-23 and I have not been able to reset the inverter to switch from shore power to battery power. I switched the reset under the port lazarette and the reset to the toggle switch to the left of the inverter. (see green button in lower right of attached photo). The inverter works fine on shore power. Is there something else I need to reset? In addition, is there a reset that is needed for the solar power. I don’t think it’s working?View attachment 28182

Has the GFCI outlet on the inverter been reset? The outlet on the inverter supplies power to the AC 120-volt panel. If that GFCI is tripped, you won’t get power from the inverter.

Is this green button the GFCI?

I should add that the toggle switch doesn't "click." Can that switch burn out?

It’s the reset button on the outlet next to the black plug on the Kisae Power inverter. Notice that there is no green light illuminated on the outlet, just below the word “Power” on the inverter.

Dumb! I didn't see ICCH button. But it wasn't tripped and there is still no power to the inverter. But here is the history of the problem.
Electrical Problems: 2020 Ranger Tug R-23

The problems began in April with gas filling cabin during external battery charging. All batteries were replaced and with event apparently tripping various circuit breakers (e.g. thruster). However, the 12-volt option on the inverter no longer functioned. I attempted to reset the inverter according to factory instructions, but the inverter wouldn’t power up with the toggle switch necessary to turn on the inverter unresponsive. Power was available with a shore connection, but not available without. Subsequently, power to the helm (windless, horn, Garmin screen, etc.) also absent. While I’m not certain about the windless, horn, pump functions, the Garmin screen did work, but later lost power when boating and now no longer functions. I have checked and rechecked various circuit breakers and CDCI button to the inverter (e.g. under the port lazarette) and on the inverter, but no luck. Any suggestions?

A few things to clarify here. The main AC panel in the mid-berth can receive power from either shore power or the inverter, but not both at the same time. When the boat is connected to shore power, the inverter may still be powered on, but it will not be supplying AC power. The dash switches and DC fuse panels do not get power from the inverter. Having them stop working means the main house fuse or thermal breaker had tripped. The inverter supplies power to the hot water tank, cooktop, outlets, microwave, and air-conditioning unit (if installed). Based on what you’re describing, I suspect the inverter battery switch may be in the OFF position. This switch is located inside the port cockpit hatch, next to the resettable thermal breaker. I would recommend checking that switch.

Thanks for the quick reply Jared. But I did check inverter battery switch, and it is on. But the green light on the inverter doesn't go on when I press the green power button on the inverer and the toggle switch next to the panel doesn't respond. In sum, I don't seem to be gettting power to the inverter. Is it possible that the technician who installed the new batteries missed a connection. I'm also baffled about losting power to the helm panel—windlass, horn, Garmin display, etc., even connected to shore power. Could the bad battery that created the gas emission damaged the inverter itself?

I would recommend having the technician go through the boat and thoroughly inspect the wiring. It sounds like something may have been overlooked or wired incorrectly during the installation. Since the dash is also not working, I would recommend checking all fuses, wiring connections, and electrical components to make sure everything is properly connected properly.

Hi Jared. Update on inverter reset on 2020 Ranger Tug R-23. The technicians at my marina finally got my electronics working. Accidentally. I’ve spent the last 3 months trying to reset my inverter after a battery event killed them all. I replaced all the batteries. I’ve reset the various switches, had the technicians try to figure it out, gotten advice from the Tugnuts and Ranger Tug people, but until now nothing worked to resume battery power to the inverter. Then, trying to help, one of service people reversed the steps in inverter switchover. After disconnecting shore power, instead of the approved sequence of remote switch followed by the inverter switch on the panel, and not being aware of the “approved sequence, he turned on the panel switch first and then the remote switch. It turned everything on. In fairness, I do remember a thread about resetting the inverter on Tugnuts where someone suggested reversing the recommended sequence, but not seeing that anywhere else, more or less dismissed or forgot about it. It should be more widely known.
