My brother and I installed 8 panels on his Cabin in the UP. In another thread someone suggested this system. I wish I could find the thread so I could credit them. It's not cheap but it worked PERFECT for the 8)- 65" by 39" panels we installed...

Another JBD 7S-20S 200A problem. Everything looks good voltages are good , all cells are reading fine. BUT when I turn on my my Growatt SPF 3000TL LVM inverter the relay starts cycling. The growatt comes on just fine but it sounds loud and incorrect so I shut it down. I haven't tried to pull a...

I am using a over kill BMS and installed one on my brothers system. I'd like to find a BMS that would allow me to pull more than 100 amps for a while. I was looking at this from Docan "(USA STOCK FAST UPS DELIVERY JBD 7S-20S 200A 21V 24V 48V 60V 72V Smart BMS Balance Board Protection With...

While I was removing the start switch from my JK Smart Active Balance BMS Board 3S-8S 200A 2A Balance Current (JK BT 3S-8S 200A 2A) The socket came off of the PC board. with so many 6 pin plugs and sockets out there I'm having no luck finding the type of socket so that I may replace it. Has...

I have my 24 volt battery built. I need to order an inverter. I had finally decided on the Growatt 3kW Stackable Off-Grid Inverter | SPF 3000TL LVM-24P. But I just watched a Signature solar video on YouTube that recommended using a separate charger for charging the batteries when using this...

I bought a JBD 7S-20S BMS from Docan. The link in the manual gives me this screen Amy from Docan sent me link with the new software but it will not connect to the BMS. It show connectable but. No joy. Is there any way to get into the settings with the app I am showing in the pic ? I've...

Overkill BMS and xiaoxiang software are giving funny readings sometimes. I charge my 24 volt 100ah battery using my growatt solar inverter. After it's all charged, and in about 4 hours (edit: with the inverter off and no usage) , I look at the app and it's showing 65% capacity. Seemed odd so...

I have a new google pixel 8 phone. I'm trying to find the ENJPOWER app to install on this phone but so far I've had no luck. Help please. I've done several searches but most threads are just talking about settings on their system and not the app. Thanks -K

Batteries are advertised as 200ah, The sticker in the picture show 197ah 3.2 volts and the data sheet shows 202ah* . LOL

I just finished testing 17 - 250 watt solar panels I picked up at Santan's Savannah facility. Very happy: At solar noon each panel output between 212.5 worst and 227 watts best. For September I thought that was good. Just FYI . I've bought 33 panels from then and have had no duds so far.

I just spent 2 weeks in South Africa. The ranch I was at was thinking of going solar as their power is turned off for "Load Shedding" for 4 hours a day. This is the odd part. If you put solar in you are still required to pay a monthly fee for not using them. $50 to $100 a month. TIA ... LOL

I built for my brother and we installed a off-grid solar system using a 3000 watt growatt all in one. Until he gets some trees moved we're going to be a little shy on power now and then and have to use a generator what's the smallest generator that someone has experience with that will work...

I have a 24V Growatt SPF 3000TL LVM All in one and overall it has been working fine. I am using 8 Lishen 200ah cells and a JK BMS. Everything works but one annoying thing I cannot get the system to stop doing is use solar instead of the battery. It will get 90% +/- charged maybe even 100 % +/-...

I have a class A motorhome with a Southwire 41301 120v 30A transfer switch. The Motorhome has a generator and thus the need for the transfer switch . My problem is that when I plug the Motorhome into my Gro-Watt inverter the transfer switch displays a open ground and will not engage. I've tried...

I'm a retired tool and die maker and designer and in a few months my wife is going to retire. Our dream is to buy 25 to 50 acres of land and camp there and travel with a travel trailer. I really enjoy geeking out on this stuff while watching one of Will's videos 4Patriot power came up. It seems...

I want to build a 24 volt input 240 split phase output system. I'm going to be using this 100% off grid and want to make it so I can just plug my RV into it when I am on my land. 3000-4000 watt output is fine. I was going to use Growatt but after seeing Will's video I gave up on that. I started...

I am hoping they someone in this forum has already solved my problem. I build a system around Signature Solar's prebuilt 24v100ah battery. They no longer offer it. I want to build another system for my brother but am not having much luck finding raw cells in the 100 to 105ah range. Docan...

The app screen on my phone is overlapped and hiding what is underneath. any ideas on how to fix it?

I noticed that when I selected start a conversation it looked like it was going to be a public conversation. Is there a way to private message a user on this forum? Thanks .. K

I have a problem that is driving me nuts. I have a “JBD 7S-20S 200A 21V 24V 48V 60V 72V Smart BMS Balance Board Protection With Bluetooth” installed on my 8 cell 200 ah LiFePo4 24 volt nominal battery pack. As anyone who has one of these BMS’s it has a relay to handle the higher current. My...
