True, if it's off grid, the multi-Plus is the best option if you're on a budget (like I am). There are a lot more used MP 3000 on the used market then Quattro so they don't resell it for as much. I think the Quattro is built better but victron is already a quality inverter.

Is that before or after you derate the wire? Anyway, it's not particularly unsafe and with that long of run wire is expensive. That's why you're getting the voltage dropped though. 10 AWG is your standard size/smallest typically used on houses solar wire. 535 watt panels are some big panels.

A Multiples not Quattro inverter? I thought the highest 120V MP was the 5000 (4kw actually) available in 48V only. The smaller multi pluses are usually cheaper per kW on the used market. But they're made up to 1500 (12kW) in 240 volt 48V.

A lot of building codes require the wire to have circuit protection 1.56 times ISC. 10 AWG solar has a maximum of 30 amp SP if ran outside. This makes the maximum panel IEC 9.61A when paralleled (19.22 total). Panels above 350 watts (sometimes less sometimes more depending on number of cells and...

Shouldn't be 10% that often at all. Do you mean 2 400 watt solar panels or 2 200 watt panels. With 800watts of solar you are definitely "over paneled" for a 2000 kwH battery. If your battery is 12 volts it's ok to charge with 15 amps. If 24V 15A would be a little high for lead/AGM but ok for...

I got a Multiplus off eBay for cheap. Fingers crossed it works... The European voltage multiplexes come in higher wattages. You could buy two Multiplus 5000s. (their only 4kW each I guess) or 4 Multiplus 3000s (2.4 kW x 4 = 9.6kW)

Does the seller have any left. Could you get a 4th panel and series parallel (2s2p).

2 sets of wire is two strings not three.

2s2p is 4 panels and 3s2p is 6.

Check out Cable Cabana on eBay. They have pretty good prices. While there are some bulk wire websites that are cheaper, the ones with the cheapest wire often require large order minimums. In my case Hawaii is usually excluded from the free shipping.

The difference in voltage drop between 94V and 142V is insignificant. The main determining factor in voltage drop is amperage. If you add another PV circuit (2s3p/3 circuits) you will have the same average per circuit as 3s2p. It might be cheaper to buy a higher voltage mppt then the wire...

Thanks for the reply. I had read that when I was first getting started it is very helpful. It says to change the cells at 3.625. Other places say 3.65 as does the seller of the cells I'm using. I'll turn the voltage down to 3.63 (my charger doesn't have 3 decimals) if I have to leave them...

Thanks for your help. The way the charger is designed using ring terminals on it wouldn't work well. It's just bigger then a #10. I tried drilling the ring terminal but it always got very bent up or broke by the time I got it there. Also tried filing it with similar results. I don't have a drill...

Even with the full 10 amps it'll take a week to charge all 16 cells. I do have a multi-plus but I don't want to go to all the work of setting the BMS up and then taking it all apart to rearranging the cells again to top balance all the cells with each other. I'm top balancing sets of fourth for...

Thanks for your help! For some reason I wasn't getting notifications on the form even when I clicked on the notification icon. Not that anyone has to answer my question but I appreciate it. Will Prose said almost zero and other places talked about tail current. I wanted to make sure I didn't...
