    EG4 5.12KWH SOC

    I have a PV system with 1.92 KW Solar Panels, a Growatt 3000SPF ES Inverters and EG4 5.12KWH battery. Don't know why the Battery SOC lights only 3 out of 4 lights light up when the voltage reach all the way to 55.8V which is already 100%. Never goes higher. I only see it went above 55.9...

    Murray 200A Main Service Panel JA2442B1200SEC/FEC

    Does anyone have the above 200A MSP manufactured just over 10 years ago by Murray, now owned by Siemens? It came with a 4-pole 200A MEQ9985 breaker, and because of 120% rule to connect more than 40A of solar back-feed breaker to the MSP, you need to de-rate the main breaker. Siemens said the...

    EnPhase Combiner Box

    Does anyone use Enphase Combiner Box 4 ? I am debating of using which one should I use Combiner Box 3, 3-ES, or 4 and I couldn't figure out the differences but they cost the same. I assumed newer Box 4 is better and I am using Q cells 360W integrated with IQ7+.

    Backfed breaker

    Not sure if I understand what a backfed breaker is correctly. Isn't it is just a breaker like one you find in the Main Service Panel that allow current to pass one way through from the grid to load? If I am going to make a Load Side grid-tie connection from my PV AC output to the Service...

    Growatt 3K LVM-ES & EG4 48V100AH -Run BMS TEST problem

    Does anyone has a GW 3K LVM-ES Inverter with an EG4 48V100AH Battery? One early morning I have a battery alarm light on (no beep). I think it is OK (unless it beeps) because when the sun goes up and the battery gets charged and then the alarm light goes off. I was panic and I tried to connect...

As you know the two spaces is for 2 independent live (hot) wires where as the output from the inverter come with just one hot wire. Do you think I can...

    Inverter Grounding

    Anyone has experience with grounding a Growatt 3000W TL-LVM-ES? Is it required? I am expecting Signature Solar to shipping my order in the next 3 weeks to hook up with the 48V 100AH EG4 battery that they sent me 2 weeks ago. My first question is: Do I have to ground the inverter? Second...

    Inverter output power and the loads

    Can someone explain this: I watched Will Prowse's video and elsewhere that they cut a 12awg extension cable to connect to the inverter output terminals. We can buy a 12 awg extension cord with 1-3 outlets. I asked Signature Solar what was the AC output and the answer was 120V 20A. That would...

    Using a Load Center

    I ordered a Growatt 4K 3000TL-LVM- ES and a 48V100AH battery last week. I plan to install a 70 Amp or higher Square D Load Center with a 10 AWG wire from the inverter to tap the power onto individual circuit outlets instead of cutting a 12 AWG extension wire to branch it out. Does that make...
