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...

So you have 4 strings of 3 panels at like 72v 14A each string. They all travel 65 feet separately, on a total of 8x 10awg conductors...

i just ran 13.3 amps, 72 volts for a 65 foot circuit using #10 and got 2.5% voltage drop. Are we talking about the same thing? Again...

That chart is wrong. It’s for 12 volts. Go to the south wire (or any other calculator) and run it using the actual voltage.

East West orientations are mostly overrated for off grid. West can help for an undersized hybrid system when there are TOU rates...

I'm not familiar with those inverters. However, the general rule is that you mustn't connect or disconnect MC4 PV connectors whilst...

As I understand it, everything inside the house has to be in metal conduit. Flexible is ok too, not just emt.

6% difference in estimated SOC isn’t significant. Heck, it’s probably a rarity that they’re that close.. I’ve been open loop with my...

Traditional solution is to start with bonding and shielding and grounding. Wider conductors offer lower impedance to rf-that’s why you...

I think you may be shooting yourself in the foot. I've noticed that on bad solar days (when you want to be overpaneled) the mppt runs...

I don’t think it’s possible to know at this point ..to many variables and different levels of quality out there… there’s not enough time...
