Watching a PYS video (which are great) Jeff emphasized installing a switch in between the inverter and un-switched DC terminal. Has anyone done this and I was thinking about using a 30A Breaker with manual reset. Thoughts? and where is the un-switched (24/7) DC terminal bar?
 
I may be misunderstanding the question here but my 2017 R29 CB came from the factory with both a rotary switch and breaker between the inverter and the battery + terminal. Is this not the case on your R23?

“The PROwatt Remote Panel (remote panel) can be connected to the PROwatt SW Inverter via the Remote port on the front panel to turn the PROwatt SW Inverter ONorOFF.” Per owners manual.

This is not a hard disconnect between the bat and inverter. What happens if this fails?
 
The installation should include a on/off battery switch between the house battery bank and the inverter. A fuse should also be installed between the battery bank and inverter. This fuse would be greater than 30 amps. It should be around 200 amps if it is a 2000 W inverter.

The 24/7 is located in the mid cabin behind a panel.
 
Per BB Marine and consistent with Jeff Cote’s advice, that is exactly the configuration I have on my 2012 R27. I keep the inverter switch OFF unless I am using it. GF
 
Gary, your inverter is powered from the house/thruster bank +12v bus bar in the battery compartment via an ANL fuse and a disconnect switch. Since you have a stand-alone inverter and separate battery charger it is OK and a good idea to turn the inverter switch off when not using it. Also note you have a MSW inverter, some appliances or devices do not like this and need a pure sine wave.

Thanks Howard, I did notice that I have the modified sine wave inverter. I've run a dust buster okay on the AC. My only other AC plans are a coffee maker. I don't think that would have problems, would it?

WRT PROwatt I assume that has a built in charger too (if so I missed that), which is why it needs to go to the unswitched distribution?

Jeff Cote has a video about a Nespresso machine that failed/broke 3 times on a boat owner... before the boat owner realized it was his modified sine wave inverter causing the Nespresso coffee machine to not function correctly. I'm not saying you'll have troubles, but then again, you may. I don't know that anyone can answer that.

I'm going with the cheapest Mr. Coffee straight heating element only mud maker you can find. The Nespresso stays at home! 😀
 
Sweet Pea has "blown-up" three Black and Decker drip coffee makers utilizing inverter power. We now use the machine on shore-power only, with no problem.
 
I've tried running a couple of different models of Keurig on my boat using AC off the battery. It would work kinda sorta but mostly not. I suspect that current draw is quite high during the water heating phase and the inverter can't keep up. I have a true sine Kisae inverter/charger so it's not a matter of the sine shape. I now boil water and use either instant, pour through or french press.

I have measured the Keurig that came with our boat running on the inverter on battery power alone (engine turned off, solar not working (in a covered slip, no sunlight). I used our Victron Battery Monitor (BMV-712) to measure the wattage/current draw. I saw 752 watts (62 amps) being pulled. It takes a minute or two per cup of coffee. Once the coffee is done brewing, the amperage draw stops and voltage bounces back up to normal.

Wow, so what exactly were the symptoms you call "blown-up"? Melted wires? Melted coffee maker plastic? Snap, crackle pop noises? Light on coffer maker switch goes out and never heats up again? Seriously, I just want to be prepared in case of trouble. Thanks, GF
