Just to set the record on whether a solar flare can overvolt a charger, here's a post from a member that recorded a solar flare https://diysolarforum.com/threads/july-17-solar-flare-event.65867/ so yeah, if your volt input to your charger is not far off from it's limit, a flare can push it over...

I have 3 8s banks. Out of those 3 the Docans I got from Their Texas warehouse are so tight, I don't even need a bms on them. But that was awhile back, things may change over time but they rarely ever carry the 304's I want so I'm trying a company called apexium that has good reviews & a US...

I've been using jbd bms's, good quality & nice bluetooth app. You can buy them off their site but I've had issues with them sending the wrong units. Current connect sells jbd.

Well you could swap a heater for something less consuming.

4 150/100's lasted me about a year each. They replaced the 1st 2 but not the 2nd 2, like your experience, the dealer came up with a lame excuse my system wasn't wired right. Well I got another brand of chargers & have no issues. Victron will never see another dollar from me. They might make some...

I've had good service from them as well. A bms mysteriously quit working & they replaced it no ?'s asked.

You're starting to get on my nerves! No dummie, a solar flare raises the voltage & likely the amps too, show me where that's not true, not just you're opinion.

I'm guessing you're wondering if a smaller bank combined with a larger bank will drag down the smaller bank faster? The answer would be no. The inverter will draw from the strongest banks 1st & all banks will maintain an equal voltage. The smaller bank can't be drained faster than the largers...

I'm using growatt chargers & they do the same thing, it's not very loud tho & normal I guess 'cuz they work just fine all the time. I've tried epever gear but they don't hold up very well.

I'm not grid tied but it would seem to me just a transfer switch that disconnects the grid & switches your system directly to your house load would be the answer but good 200 amp transfer switches aren't cheap.

I tried just regular polyurethane on a cracked panel I have but it blistered loose after the 1st summer so I peeled it all off & been running it like it is this past year & it's working like normal. I inspect it every so often looking for burnt traces but it seems ok for the time being. I guess...

63 is marginal. I have 75 & eventually will be 83 300+ watt panels & need every bit of it for just my tiny house & 10x20 shed. It's more than I need for on demand power but it's sure nice to have them all on bleak days & still get plenty of power where I'd otherwise be taxing the batteries heavy.

Even with that increase, you're enjoying some of the cheapest rates anywhere. My base is .055 but you get zapped using power during peak hours & even if I use 0 power, the monthly connection fee is $30.

If you have 2kw inverter, just hook 1500 watt space heater to it & there ya go.

All their chargers have overvolt shutdown but I'm using the SC48120-MPV's & they don't mention it in the specs but I had an overvolt shutdown happen presumably from a solar flare that jacked my panels past their normal VOC.
