I think I may give that battery a shot, except the 13.4 kWh model. It also has the cables included which look long enough to get to the DC battery lugs on my inverter.

Thank you, I can bump up #13 to 58. Is that advisable? The 48V chargers on the signature solar site charge to 58.4.

If you contact them, use a disposable email address.

I have 2 Growatt 5000's that I just installed. My primary goal is power storage for when the grid fails (I'm in Texas so, yeah). I have no PV panels yet, I'm just charging off the grid for now. I want to add some solar in the new year. I'm going to start small - real small, like 1 or 2 panels...

Thanks! good call

Thank you for the prompt reply. That confirms my assumptions. Much appreciated.

I am going to DIY my grid-tie system from batteries to inverter and maybe to subpanel. However, I want an electrician to tie into my main panel and the grid. This ensures everything is up to code, proper permits are in place and an overall sanity check. However, I don't want to contact a...

I'm looking at the same thing. They look like quality units with a professional case but I just can't help but think that it's too good to be true for 6.9KWh. I welcome any thoughts and especially any first-hand experience with them.

I have the quote from Seplos in my inbox. However, I have yet to hear of anyone that actually received any of their batteries. I'm going to wait to order. Too many things are giving me pause. I hope it's legit, though I will probably miss out on the $1K kits while I wait.

I'm wiring 4 12V batteries in series to make a 48V bank for my 48V inverter. I'm planning to use 4 gauge wire. However, given that it is relatively high voltage, is that gauge of wire unnecessary? Can I go with a smaller gauge and/or longer run? Thanks!

So you received your Mason kits? Were they as in the pictures and videos and did they arrive in good condition?

It's a SUNGOLDPOWER 12000W unit. 48V split 240V.

So clearly 4 gauge isn't overkill. Quite the opposite. Thank you for the illustrative pictures!

Well I'm going to DIY the basic stuff but I have a good electrician that will be tying into the meter with permits and the whole 9 yards. I know my limitations. The mere fact that I have to ask these questions illustrates that I need help with the critical parts and a second set of eyes to...

Is a 150A breaker between the batteries and inverter too small?

4/0 it is. Thank you! Now I just need to get a second job to afford it :)

I have 2 Growatt 5000 inverters and 4, 48V server rack batteries. I'm connected to the grid which is just passing power through to a 30W load. No solar installed quite yet. I just finished the system a week ago so I'm just monitoring its behavior for now. I'm confused by the behavior of the...

Thank you JGB3

Great info. Thank you. One thing I failed to mention is that I'm not confident the batteries are getting a full charge. The SOC graphs usually say 75%, occasionally 100% (25% increments which is frustrating). I'm not sure my BMS is communicating properly with the inverters. Do you think the...
