Yes, the new ones are $350+ , most people pay tax on top of it. Also, some people confuse Smart Solar with cheaper Blue Solar models, it's not the same. Smart solar has Bluetooth built in, also feature to attach display module.

To be more accurate, Lake Wylie SC, still Charlotte Metro area. Are you interested?

Selling my charger controller that I purchased brand new and used for about 6 months. I upgraded to a higher voltage unit and I won't be needing this one. It's in perfect condition, not a scratch. Asking $300 and I'll ship within lower 48 states. I'm in Charlotte area and I could deliver...

Price adjust to $1750, +shipping.

I'm selling my EVO 4024 inverter/charger. Shortly after I bought it I decided to go to 48V system and I purchased 48V split phase unit. This 4024 inverter was in service for about 2-3 months total under very light load. You're basically buying a new unit. I kept it as a back up since I thought...

Price lowered to $680.

Probably, but I really wanted to try this 10W 10 ohm resistor I had here laying around, if it can handle it , and it did just fine.

That was one of the options , but I don't have a power supply with that much voltage, max 30V.

Worked like a charm, inverter is connected.

Yes, that's what I was thinking, to check on the inverter side as well.

Ok great, thank you. I'll give it a try, maybe tonight. Would you say holding it to pre-charge for about 20-30 seconds with this 10 ohm piece should be enough? I can't hurt anything if I hold it longer for the very first time, if anything it just gets warmer or hot, right? That goes back to...

What I'm doing right now is really just a temporary solution to quickly connect the inverter to the batteries before the proper size resistor arrives over the weekend. So I'm trying to "wing it" with what I have at hand right now. Later on I may or may not build the disconnect switch with the...

This controller is for sale, never used, just updated firmware. I changed my mind and I need to go to higher voltage unit. Price is $700. You're saving about $150 , they sell for just under $800 + tax. I can split shipping cost in lower 48 states. I could probably also do an exchange for 250/70...

You forgot one important value, the gauge and type of wires used to bring power to the controller.

"Can" damage, "depending on how much was exceeded"... that confirms there is a room above 150V. How much more, that is to be discovered by the brave men of this forum :)

The only issue with this is that this array is in shade until about 9:30am or so, only then it is fully exposed to sunlight. The distance is about 90 -110 feet. Not sure exactly, I recently added even more since I was moving it and re-arranging things. What do you mean by daytime lows...

Correct, and that's what we're doing, romantically speaking, I always plan for when things go wrong and there always better be a plan B. Just wanted to see if you agree when in this one specific scenario I'm describing, the max VOC wouldn't be a problem. Of course there are many variables and...

In case of maintenance, or troubleshooting etc. I always disconnect the panels first, at least in my setup. If I always pull current and MPPT never sees the maximum VOC, then the maximum VOC is not a problem for the controller, correct? By "leave the charger off", do you mean turn it off in...

There is always charging. But let's say there wasn't, controller is reporting Vmax, isn't that the highest voltage of the array ? You answered previously there is no higher voltage than the one reported by Victron. We might be going in the circle here.

This is all more-less theoretical stuff, I know what I'm supposed to do and what I shouldn't. Just trying to see where I can push it to the limits. Doesn't mean I will. My battery and inverter can feed what I need to feed with power, the panels are the weakest point. I need to squeeze as much as...

I wish my battery was ever full after a day of charging. But regardless, it only climbs to a point. And that's what the this whole discussion is about, finding that point of max VOC. With 5 and 6 panels.

I'm not sure I understand your question, or the point of it. Can you elaborate?

I understand what VOC is, and if charge controller is capturing and logging the highest voltage during charging, then my method of measuring should be correct. Where I lost you is when you're telling me I should measure the highest voltage disconnected from the charger. What do I achieve by it...

No this was with charging. You think charger is getting even higher voltage than that and not reporting it? Why would they build it that way?

Looking at Victron app, the V max for this array today was 116.07V, that's the highest of the week. Adding another panel would be getting close, but still safely under 150V I think. I'm not planning on risking it, I'll most likely make two 36V arrays from 6 panels to be safe. But just...

How about monitoring it with software and logging the highest voltage of the whole array for the day, that's what I'm doing right now.

Only reason, for now, is not wanting to add another set of long wires to another array. If I add a sixth panel and voltage gets dangerously high, I'll split it into 3+3 panels into 2x 36V arrays, this should max my 150/35 controller at around noon. I'll still have one set of wires going to it...

It is winter here and this is probably as cold as it gets here, with 5 panels I'm stable at 95-98V, occasionally jumping to 105. Maybe I'll give it a try with the 6th one. And if it fails, I'll have a reason and excuse to buy a new controller :). I'll probably go for the biggest one , 250/100...

With 5S I'm at 105V max, monitoring for 2 days now, I'm thinking adding one more shouldn't top 135 -140V in any condition. Btw. , what happens to the Victron controller if 150V are exceeded, even if just for a quick spike ? Is it done? Cooked? Ready for new one ? :) (it's probably somewhere in...

:) I figured that much. Don't we all have these little "occasions" along the way... I guess some more than others. Don't ask me how many BMS's and cheap charge controllers I have laying around, that I will never use.

I can't, but ask your friend if he would exchange 150/100 for two 150/35, also asking for a friend.

Those are 12V panels wired to 48V array, so at most I'm getting under 90V (never crossed 85V) , that's so far at least. I don't think voltage would jump over 150V. I guess I'll have to sell at least one of the smaller ones and go for larger, I wanted to avoid doing this. They are not even a year...

I'm not sure this was ever discussed here, most likely yes. But I'll ask anyway, I can't seem to find much about this. I have two Victron Smart controllers MPPT 150-35, identical units and I'd like to connect my array that brings about 50-60 amps into it as 1 array. I don't want to split it and...

Ok, that's what I thought but I wanted confirmation from someone else. When you pair two cells into 2P and assemble the bank to 2P8S, does it matter where exactly is the lead from BMS connected to each 2P cell? My logic (maybe incorrect) tells me that exactly in the middle of buss-bar joining...
