    Growatt 3000 SPF Floating Neutral (Solved for Now)

    I used 3 different QR code reader apps, and all come back with no matches. Not very impressive. :rolleyes: I can only speculate it is the newer model since I don't have option 24... A follow up question if you don't mind... If I implemented what Chris did, Would I connect an additional...

    Growatt 3000 SPF Floating Neutral (Solved for Now)

    I really appreciate you folks tracking this down! ChrisG states that "when I jump the neutrals AC input and AC output on the growatt," ... What does that mean exactly? I have a plate/sticker on the side, but the model number is nowhere to be found. My SPF 3000TL LVM-24P is about a month old...

    Open Ground from Growatt AC Output...

    Hello! I was going to charge the Tesla with the Growatt off grid system , but the Tesla Mobile Charge gave a Flashing red T on the charger. This means that "there was a ground fault circuit interruption due to an unsafe current path." I purchased an outlet tester and indeed the tester...

    Adding Parallel String... Fuse?

    I was getting ready to install a second string to my Solar array and I recalled reading that I needed to fuse between the strings. The panels will be 3 in series with two parallel strings. The Vmpp for the panels are 33.12 and Impp is 9.36. If I do need fuses, what size? 30A? I also read...

    Growatt and data export.

    Hello, Attempting to export the data from PVkeeper results in an unhandled exception. No data is exported. It is nice to see realtime results, but I can't export the history. Is there a solution or an alternative data logging option? Thanks! When I try to

    Wire from Solar panels to Charge Controller

    Hello, I need some wires to go from the panels to the CC in the garage. The ultimate configuration will be 3s2p... Each string will be ~100 volts @9.3 volts. Two stings should be ~100 volts @18.6 amps. Would the attached link be a good choice to go from the panels to the CC...

    New Q.Peak Duo-G5 panels.

    I will be using the SCC build into the Growatt 24V SPF 3000TL LVM.... Sure wish I would have taken a couple EE courses in college....

    New Q.Peak Duo-G5 panels.

    I think my best course of action is to start by adding one panel to the charge controller. It is a 24V system and the VOC is 40 per panel so that should work. The goal is to have a 3s2p configuration.

    New Q.Peak Duo-G5 panels.

    Hello! I picked up a half dozen of these panels today. The voltage measures accurately , but there is no amperage... Is there anything special about these panels?
