Not to thread jack but do you just put a 40 amp fuse (for a 30 amp application) between shore and the inverter to protect your rig from burning down?

Very good advice. Can explode and burn down house and also electrocute you. Solar can be safe if we do it right.

Skip to about 2:00minute part.

I like youtube lots of info on that site.

Don't forget to look at marine salvage too. I have two old but good xantrex inverter chargers paid 10% of new cost for them. One is used, one was installed on a brand new mega yacht, but they changed mfg so they pulled mine out and replaced it with the new mfg.

Wait what do you mean? Do xantrex have life time warranties or something? Can I just buy a banged-up broken one offline and then send it into Xantrex and they'll give me a new one for free?

xantrex is just a good brand, they put them in a lot of m h. the bigger the battery bank the bigger the charger you need. when looking for a inverter/charger also look at the charging amps, if you have a big bank go for a charger with at least 75 amps dc.

Inverter/Chargers depreciate quickly, so I was able to buy a $3500 new cost xantrex inverter/charger for $350. It has never been used, I realize you misread my post, all I was saying is that they depreciate 90% on the used market, same with my Xantrex Freedom inverter/charger, paid 10% new cost for it used. This is their top of the line stuff, not the little ones you plug into the cigarette lighter. A big advantage for me is that they have 3 stage charging, which is important if you are bringing back a dead battery pack or battery with Epsom salts.

I got both of mine off craigslist with the amp hour meters. The larger one is 24v pure sine wave and weighs a ton and the other one is a marine 12v. They are charger/inverters. This was quite some time ago, but older inverter/chargers depreciate fast, however they will do the job they were made to do and they were made in Arlington, WA not China if that means anything. I cannot compare with the new China ones, but I suspect using new technology, but I don't know and definitely alum windings compared to mine which are copper, but do we care?

I have a Xantrex XM1800 from another application. I route shore power into it via the picture attached....I switch between genny/shore by unplugging the 110AC from the Genny and that becomes my shore power line.

This unit will automatically cut off when battery power drops below a programmable voltage, switch over to AC when available, charge DC if AC is available. It really is a nice little unit. I have not used it in any solar applications. That's for summer 2018.

Remember with inverters they have mounted close to the battery, you can't run DC wires a long distance. You can run your AC wires long distances.

Looking at marine salvage is a great idea. Hodges Marine sells the XM1800 for $305.00
