OK, so about #2 ‐ It depends what you want to do. If you are doing serious maintenance (like rewiring) then yes, you will want to turn...

I use the MTS on the OUTPUT (to loads panels). I'm not understanding your intentions... Can you scribble a diagram of your setup?

Great. I use mine solely as a manual transfer switch. I do not count on it to be a breaker in case of overload. So I have proper...

Yes

This is when wired incorrectly. Most DC breakers for PV use are polarized, meaning that the direction of power flow matters. So you need...

I use this as a selection switch for the output (to loads): https://www.aliexpress.com/item/1005002992599504.html Basically it's a 2...

I wonder if this helps prevent degradation in Lifepo4 too...

Finally got to connecting everything: Time-delay relay, Tyco Contactor, and a voltage sensing relay for low voltage cutoff. The low...

My solution using the time-delay relay solves this too. Basically, whenever BMS discharge is enabled, and main DC breaker is ON, there...

Can't you achieve the same goal by pushing the data to HomeAssistant via MQTT ? I know it's also possible to change inverter parameters...

Let me guess what happend: Your Lifepo4 ground was connected to chassis ground, just like your starter battery, right? I blew up a CC...

I don't think you need a boost converter. You should check to see what voltage your alternator outputs. Also, these boost converters...

You paid alot for those Victron SCCs, make good use of them: If you have "smart" BMSs with some kind of communication, you should be...

I have a small 1.3kwp array, so not much choices... Maximum PV voltage (VOC) is around 85v, inverter max is 145v. I prefer these lower...

Yesterday I conducted another experiment with the V2L. It was a dismal day, not much solar to recharge the home battery but the...

I thought it wasn't a thing until Lifepo4 batteries came around, having low internal resistance and a high discharge capability. Of...

Yes, you should have an MCB BEFORE the SPD. That's because the SPD will by design short the line to ground, should a high enough voltage...

I think the inverter does care - won't that high inrush damage the capacitors, or at least shorten thier lifespan?

I installed shunts with monitors on my incoming PV to give me a quick readout.

Thanks. I've seen documentation regarding battery voltage calibration on some inverters, but nothing on PV amperage. I guess I'll have...
