Put 2 more 200W panels on. 1200W for 400Ah of LiFePO4 should be about right. Runs my 15k BTU A/C, fridge and some lights just fine.

I redid my RV system moving the batteries. While I was removing the existing 4/0 battery cables I noticed one of the wires was not tight in the lug. So I gave it a yank and the cable came out. I thought I had redone all my crimps with my Temco hydraulic crimper but must have missed one. So I...

I drunk bought a Temco hydraulic crimper. I have used the Temco mechanical crimper, the one that uses a hammer that Will recommends. I have 4/0 cable and all seems well with the crimps. Is there a compelling reason to redo all the crimps with the Temco hydraulic crimper?

I installed my Lynx distributor today and decided to replace my Blue Sea 250A circuit breaker with a 400A class T fuse. The class T fuse holder is from Blue Sea Systems and the fuse is a LittleFuse 400A class T. Got it all hooked up and tested DC only, Solar and low power AC. All worked...

Finally got my MPII 12/3000/120x2 in and got it installed and working. Why didn't I get this in the first place? Hookup is easy: AC in from my shore power, AC out to main panel. That's it. No sub panels, no transfer switches. Other than 6/3 Romex being a beast to work with and the Victron AC...

Was out at the camper doing some testing of my new Battle Born current limiter. It works great and my BMSs never go into protect mode now. No precharge required. I know I can run one 15k A/C off my Champion 2500 inverter genset, but it cannot run that with the residential fridge. With the MPII...

I just went through my system diagram and put current prices on all the kit. $6550 plus tax. Add another $450 for mounting hardwire, wires and misc. and I'm at $7k for a 1200W solar, 400Ah, 3000VA system. Then I look at my little 2500W Champion inverter generator and wonder why I just didn't get...

Since my post was deleted in the censored thread (which seems to be the preferred method of discussing climate change), I'll just post this here: Like we make a hill of beans difference in the grand scheme of things. Mother Nature always wins. Did anyone ever consider that maybe we are...

I had to buy 4 of these and only need one. They can be used to make an adaptor that allows you to use the Lynx Distributor LEDs without a fancy BMS or shunt. There's a video online for how to do it: PM me your address and I will put one in an envelope and mail it to you...

I was under my 5er yesterday pulling off the corroplast to check out the workmanship of the underside. Turns out they did a nice job. With the corroplast off, I had easy access to my tanks and started thinking about upgrading my tank level sensors. Found the Cerbo GX Tank 140 and bought it...

Well, I got around to swapping out my original BMSs without bluetooth to replace the bluetooth ones. I can now turn on the inverter without using the precharge as long as both 12Vx206Ah batteries are connected to the buss. Still won't work on a single battery. But that's better than the BT...

I am going to install an MPII and was looking at my inverter precharge circuit. As it is wired now, the precharge applies power to all DC circuits when I push the button. Not sure if that is good or bad. I could add a cutoff switch on the invert + wire and put the precharge output on the...

I spent the last 2 weeks cleaning up the DC power system on my 5th wheel. Took out about 50 ft of wire and replaced with a clean install with 10' of total high amperage wire. Next step is to add solar. I decided on the 400W system recommended here from Rich solar. Updating my diagram, the...

My system diagram has gotten cluttered so I decided to separate the diagram by function. I attached a .pdf but it looks really cool when I do presentation mode in powerpoint. Clicking to the next slide adds a system. Thought I would share the .pdf. Can share a powerpoint version if anyone...

Just went out to check the camper in storage. Been sitting there unused for 18 months. My 2xSOK batteries were still at 13.5V. So they survived 2 winters without being charged (or used). Pretty cool. And last winter it got really cold (-20 deg F). We will be using them again this season.

Everything is hooked up in the electrical bay now. Two questions: 1. The covers for the battery and shunt terminals I bought are ugly and don't really work well. Any idears for what to use? Or do I even need covers? I am thinking about installing a plexiglass door to cover this...

Can I use 2/0 between batts and then 4/0 to the distributor? 4x100Ah batts.

I was trying to test my system to see if my 2x12V 206Ah SOK batteries could max out my inverter. I was able to put a constant load of 2000W output (2378W input) on the inverter with my microwave and electric fireplace (on low). I hooked up my heat gun thinking I could adjust it to max out the...

I am installing a Victron Multi Plus II 12/3000/120x2 to replace the two Xantrex inverters and converter/charger I have now. I put in a precharge circuit for the Xantrex inverters. With the Victron, will that be necessary? None of the Victron schematics show a precharge circuit, but who knows?

I am cornfused. My system is all set up for LiFePO4 charging and I rarely ever see more than 13.6V charging. I think I have seen 14.2V once in the last three years, although I don't watch the voltage 100% of the time. So why do folks have to replace their stock FLA (non LiFePO4) converters...

I installed a SOK 206 Ah LiFePO4 (LFP) a while back and it worked great. I had used cheapo cutoff switches and circuit breakers, so I swapped those out for the good stuff. Specifically, I replaced the generic battery cutoff switch and 100A circuit breaker coming from the battery with a Blue...

I am thinking about adding a Victron smart battery protect to my system. I would add it to the wire going to my DC distro panel. I won't add it to the line going to the front with the DC motor loads on it because that is also the line from the DC-DC charger from the truck. I could add a...

I added the current limiter to my inverter and have it installed temporarily. The positive wire to my inverter is one foot long. To install the current limiter the way I want, the negative wire will be 4 ft long. Is this an issue?

I looked in the FAQ and could not find the answer to my basic question. I feel stupid reading all the threads saying xx kw system and not understanding exactly what that means. My system on my RV (5th wheel): 800W solar (2S x 2 each with its own 100/40 MPPT SCC) 4,944 Kwh LiFePO4 batteries...

When I was doing my energy audit, I listed everything that could draw power in my RV. Makes sense. But the audit spits out a huge inverter size (>4kw). More than I think I need. Here's the issue when I list all 3 power hogs in the RV: Microwave: 1325 watts for 15 minutes a day Keurig: 1500W...

I finally got the 2x200W Rich solar panels installed on strut channel. All hooked up and working. I have another 2x200W Rich solar panels with 40A MPPT on the way. That will give me 800W and 2xMPPTx100V/40A. I decided to run 2 sets of 10ga wire from the roof, so each SCC will have its own...

This is on the roof of my RV. I have two Victron 100/50 MPPT's. Two sets of 10ga wire coming off roof. Panel specs: Voc: 24.3V Isc: 10.2A Vmp: 20.4V Imp: 9.8A So I am limited to 3S max. With 8 panels, I was thinking 2S/2P would work well. So, which ones to 2S/2P? This is the...

I have a full Victron system on my RV with a Cerbo GX and display. I got a Raspberry Pi to play with and installed the Venus OS to check it out. Works great, but I have not hooked it into my Victron setup. Just wondering if there is something that the RPi + VenusOS can do that my CerbGX...

My system has 2 Rich Solar 100/40 MPPTs with bluetooth. I can only see one SCC using the Renogy app that Rich Solar recommended. I have the option to add a device, but it only sees the one SCC. Would like to monitor both. I'm sure there is something simple I am doing wrong. So how do I...

My guess is no. I think I am over paneled with 3S and might be over voltage (or too close for comfort) @ 4S.
