Looking for torque specs for the lugs on an MPPT solar controller, don’t want to over or under tighten. They are Phillip head machine screws. See photo, worst come to worse I’ll just guess (been doing that for years :) sometimes with mixed results.

Thanks, great feedback.

I’m planning on mounting 3 panels on the roof of my Casita Freedom, and was looking for suggestions on holding down the cables as the route fro panel to panel prior to connecting to the cable entry gland. Being a fiberglass roof, I don’t plan on any holes other than the gland. Thanks HW

Does the fuse get installed between PV and MPPT charge controller or MPPT charge controller and batteries!

Do you have any suggestions on what type of metal bolt to use to make the connection to the bus bar? I need a 3/8” x 1” bolt & nut. Was thinking I might need brass, bronze or aluminum, but I may be overthinking this?

Well I finally solved the false reading on the 4-lithium battery bank. Once I was able to get to the battery bank, I reset the 4 individual BMS buttons and that corrected the issue. I assume that at some point one of the batteries was discharged too much. I’m now going to re balance the...

There is a number of them I’ve already found, what I’m looking for is a recommendation from someone that has used one.

I’m looking for a recommendation for a MPPT dual battery charger that you can change the priority of which bank gets charged 1st. Also can charge lithium and AGM. 30 amp should be enough as I expect to have 250-280 watts. Thanks

You’re right, I believe that a 100amp fuse came with the inverter. I will check, thanks for setting me in the right direction.

When I looked at your “best” diagram and saw that the connections are in the middle between 4&5 of the positive and the middle of 1&2 of the negative, I tried to in vision how to actually make that connection, I read later in your post a post from SolarRodthat showed connecting the batteries...

I wonder how I determine how wide/think of a busbar for 4-105ah batteries. I guess I need to figure for what 50 amp’s?

Ok, I like it. I’ll wire the fuse into the positive and look on how to fabricate or buy a long copper busebar

What is the best way to wire these 4-batteries? What is your feeling on these battery balancer/optimizer I see advertised? See photo, if you look hard I added notes for Shunt & Fuse.

Well that’s good to know, I tried to get instructions from battery company, but it was a little vague. Glad for the forum and thanks for the help

Yes they are identical batteries, all purchased at the same time from Lion Energy and are the Safari UT 1300’s So if I use this as the correct wiring for 4 battery parallel setup, where do I put the shunt? hw

So the Red & Black wire connect to a Renogy DC MPPT Charge controller that allows for the lithium bank to be charged by both the Alternator on the Tow Vehicle and Solar Panels at the same time. I like the idea of using a clamp meter to see if there is a draw.

Answer to #1 1-AIMs Inverter & 1-Stock converter for distribution and charging of the AGM house battery. The inverter is used to invert the lithium batteries and provide 120 when off grid. Answer to #2 0 = OFF no A/C power from either shore power or AIMs inverter from Lithium battery’s...

Sorry for what looks like a bowl of spaghetti. Appreciate the help and advice. Everything was fine for 2-3 years, than last thing done was add AGM house battery and a 2nd battery meter. Anytime I’ve had an issue, when I went back to last thing done?!?

Will work on that later today. Just went to trailer and checked, monitor said lithium (4-batter bank) was 70% turned on power to that circuit and inverter kicked on and it went to 100% in 15 seconds, telling me that they probably not at 70%. This only started the day I added a shunt to the house...

4ea 105ah 12v lithium batteries wired in parallel, same mfg & same type bought at the same time. All brought to depleted charge when set up

I have a Casita trailer with a new 105ah AGM House battery plus 4-105ah Lithium Batteries in a bank tied to a 4000 watt AIMS Pure Sinewave Inverter & Charger. A year ago I installed a Renogy Battery monitor on just the Lithium bank (with a shunt) and everything was fine & worked as expected...

This is the link for the Affordable DC Generators, and a very helpful team. I did find out from Renogy that I need a battery in the system as it uses the starting battery as a "relay" ?? The system reads the voltage of that battery and doesn't "forward" the excess volts through to charge the...

i watched your video on this Renogy product after I had purchased, got my Casita all wired up and the tow truck ('10 Tacoma V6) being wired now. So I also started building a DC Generator with a Honda Engine and a kit from Affordable DC Generators, that give you the platform to hook to the output...
