I have the LV2424 all in one unit. This has an automatic transfer switch built in and configuration that let's me control when the unit pulls from utility or the built-in inverter. I'm going to have a shore power connection and a generator, which I will connect to the utility side of the...

I was wiring up my BYDs for my new BMS when I accidentally let go of one of the lines I had attached to one of the cells as I was attaching it to a terminal block. It swung down and welded itself to the main positive terminal. Suddenly smoke was pouring from the battery. I quick grabbed the wire...

I've seen a few discussion that have had the occasional indirect reference to the gist of this question, but no definitive agreement. As LiFePo4 batteries age, and basically just about any other battery, they lose capacity. My question for LiFePo4 batteries is how this capacity loss is...

So, in my infinite wisdom, I managed to "misplace" the cable that connects the shunt and the monitor. Please don't ask how, that's the super genius part. Can anyone who has one of these take a look and let me know which pins connect to which? Then I can make a cable to replace the one I...

Anyone know of a source for about a 5"x3" ceramic heatsink? All I can find are the little ones that are sold for Raspberry pi, or similarly sized ones for power transistors.

I ran into this blog from a person who improved his fridge efficiency. Thought some of you might be interested.

For those of you using Blocking Diodes you know that there is a constant power loss from them. Unlike Bypass Diodes, Blocking Diodes are under most circumstance forward biased, which means they introduce a .4 volt drop in each circuit. If you are pumping a lot of amps through your panels then...

In my quest for information on working with used solar panels I've come across a number of useful YouTube videos that may be of use to some of you. Hope you find these useful and educational. Repairing a lightning struck panel, specifically replacing the fried junction box. Fixing solar panel...

I'd appreciate any feedback that could be provided. This is based on combiner boxes I've seen on the web, and is intended to be put on my trailer. My main issues are as follows: Are the blocking diodes required? Some boxes have them, some don't. The intent is to stop reverse current in the event...

The help does not seem to cover this. How do I specify a search that only finds matches when all search terms are found? i.e. I want to look for LED lighting. But I get results for anything having LED or lighting. I've tried double and single quotes "LED lighting' 'LED lighting'. No joy. I've...

Since the Solar Panels have reverse diode protection in them already, what is the purpose of also having these in the combiner box? Diode forward voltage drop is typically close to .5 volts, which when multiple by 4 and then, in my case 15 amps per line results in an additional 30 watts power...

I'm planning my Solar Array wiring. I'm at the stage where I am identifying parts for purchase. My array will be a 2s4p, so 4 pairs of lines coming into the combiner box. I want to put fuses on each positive line before attaching them to the bus bar. I'll need a 20 amp, 60volt fuse holder...

I have free access to sufficient bare 14AWG wire to be able to build my own equivalent 1/0 cabling, by combining 9 wires into one cable. I figure electrical tape wrap, then heat shrink. According to tables I've checked, single core 14AWG will carry 24 amps max, 9 lines thus providing for 212...

I’ve been thinking, and as my wife would be the first to tell you, that can be a dangerous thing. Mostly, she says, because I’m not equipped for it. This is with regard to the various parallel and serial cell combinations we throw together in order to achieve our needs. And in particular with...

Most of the manuals mention not mounting on flammable materials, which tends to rule wood out. Metal seems obviously a non-starter. So what are people mounting their mppt, breakers, inverters, etc. to?

I purchased a ISDT BatteryGO BG-8S to be able to monitor my cells, but it did not come with a cable. Does anyone know the proper name of these cables as I have been unable to find any on Amazon. The only ones I found were close but had 9 ridges in line with the 9 connectors. The device I bought...

This is going to seem an odd question. I am planning a method of mounting my panels to my RV roof, but am unable to find some information I need. When driving, or even in high winds, the air rushing over the roof will create a force trying to lift the panels off the roof (I’m thinking of the...

The All-in-One MPP sub-component quote an input voltage capacity which can be quite a bit higher than the end voltage presented to the batteries. My question is: What voltage ratio is most efficient? Should I be going as high as I can, or should I just go with a comparable (i.e. 12 volt panel to...
