It is a little bit chilly in my office this morning. I have only run it while I am in the room so far. I can reach over from my chair and put my hand on it ... the Victron is running for about an hour just powering the computer and network gear, so about 140VA continuous. It isn't even warm...
I just charged up a pair of the 12v 100Ah. One of them took a couple of trys to get to full charge, but both now seem to be fine.
I found a reference to Eco-Worthy in their manual, so, maybe they are just a relable?
For batteries with a BMS I would buy or build 36 volt batteries for a 36 volt system. And I would want to be certain of the startup draw of the motors before proceeding.
Perhaps look at LiFePO4 battery packs for golf carts?
Victron will extend the warranty on their gear from 5 to 10 years, for an additonal 10% of the intial investment. Any dealer should be able to do that.
I don't lnow what panels they used here, BUT, a lot of these utility scale projects use panels from companies like First Solar who only do utility scale solar. We only get those panels after they have been through the hail storm.
I too would just build an offgrid system. Use the existing grid to recharge the batteries during low sun times, and as backup if your offgrid system fails.
Relax. I haven't even heard the fan come on yet. I'm just testing it here using low loads. I want to make sure all of the components work before I start laying out the cart frame. (but it did run a vacuum cleaner for a few minutes)
I picked up 2 of these. Took me a few days to finally get to charging them up. One of them charged up to 14.4v right away and the other needed a couple of charges at lower amps to finally get up over 14 volts. I have since put them in series for 24 volts but haven't done any significant...
Been dealing with a bum knee so I've been doing this in my office, sitting on a chair.
As I dug through boxes of spare parts for fuses and bus bars I realized this morning I never would have thought to do this in the house with lead acid batteries.
Bluetooth monitoring over Victron Connect is so nice!
Currently running small loads like a fan and radio. Yesterday we tested the inverter with a small vacuum cleaner that started without any trouble and pulled over 500 watts.
