Wire and fuse sizes should be determined by the current your devices will draw, not the current a device is capable of delivering. That...

I'm told that on a sunny day, it can add 8-10 miles of range. For the lifetime of my vehicle, approximately 2 weeks, I've added 76 miles...

It's normal for the current to slowly decline as the batteries approach the fully charged voltage. My five LiFePO4s only draw a few...

Let me see if the check has arrived...

I don't think that the batteries should really draw a few thousand watts when they're fully charged. I've never seen mine draw more...

My VAWT produced power at almost exactly $100/KWHR from the time I put it up to the time I took it down so it wouldn't fall on my solar...

OK a bit to unpack: 1) Never Ever mix different Chemistries into a parallel bank. Use ONLY the Same Chemistry. LFP exists in...

This is why I run open loop and avoid firmware updates at all costs. Maybe EG4 can send you the old firmware if you email them?

An M4 screw is 4mm in diameter, and the standard clearance would need a 4.8mm hole. But through a thin aluminum panel I think you could...

A battery is a battery to an inverter

Go to the website of the cable manufacturer. It will give you all the certifications, etc. For examplehere's the southwire I mentioned...

The DLO number 10 doesn’t have hundreds of strands, only 27

I don’t think the connector victron uses is robust enough to properly grip solid or low strand count wires. South wire makes many #10...

Best advice I could give you is to sell them to someone else or turn them in for scrap value, because trying to use them in a 48v system...

You need to calculate (not guess) your power needs before an inverter of the right size can be recommended.

I’ve never heard anyone claim that LiFePO4 batteries need a high charge rate, and that a slow charge will harm them. I believe that may...

The size of your array depends on your energy needs, not just battery size. Lithium batteries work well at low charge rates, so any...

I have not run numbers but I suspect his calculator is using the ABYC tables (American Boat and Yacht Council). These tables are much...

And don't forget the overpotential voltage. It's way larger than the voltage drop internal resistance and the resistance of...

Many people think that. It’s a shame that that chart is so often replicated without titles clarifying what it is. As soon as voltage...
