Hi, I'm planning to use a Growatt SPF 5000 ES with 8 x 450W solar panels input. No grid connection. I already have 8 12V/260Ah batteries here, designed for storing 'solar' energy. How do I calculate how many 12 Volt 260Ah batteries I need or the Growatt can handle? At least 4 in series. Then I...

Hello, I have 9 panels (each 450 Watts) connected to a Growatt SPF5000 ES. Also 2 lead acid battery banks 2 x 4 batteries 48Volt connected with Victron battery balancers. The problem is that during a gray day (no sun) the panels only deliver around 800 watts. This 800 watts goes to the...

Hi, I have 5 Pylontech US3000 batteries connected parallel. But the LEDS on the front show different values. The system (2 Growatts SPF5000ES) in parallel mode, charging this bank. No errors at all. What's the issue here?

I've 2 Growatts 5000ES in parallel mode. After a full hard reboot (power off / total disconnect during the night because of heavy thunderstorm), both units were switched on again this morning and came up. Everything looks fine, except there is no power output. I don't hear the relays clicking...

Hi guys, I've bought Victron equipment but I find it difficult to figure out how to connect all of them together for communication. I already asked this question in the Victron community, but all I get is a link to a document with some general information. So that's not helpful at all. My...

Hi guys, I'm still looking to replace my lead acid battery bank with LiFePO4 batteries. I live in Spain, so I cannot get EG4 batteries. But I found Tensite TS-L5000 batteries. Anyone familiar with this brand and/or this model? I have 2 Growatt SPF 5000ES inverters in parallel mode. They are...

Hi guys, I have 1 Growatt SPF5000ES with 9 450 Watt solar panels and a lead acid battery bank. It works okay, but we need more power. So I bought 8 extra panels each 550 Watt plus an extra Growatt SPF 5000 ES. According to the Growatt documentation, I can parallel both Growatts, extending it...

Hi, I just found this awesome forum, where I can finally ask questions. I'm pretty new in DIY solar, however, I do have tech background. After searching and doing some research, I created a schematic for an off grid solar system. Can some of you please take a look at it and tell me if I'm on...

Hi, I'm looking for LiFePO4 batteries that are compatible with the Growatt SPF5000ES, AND are available in Spain.... I found Pylontech batteries, but I'm not sure if they are compatible. Any suggestions?

I have 8 x 12V, 260Ah batteries. 2 banks of each 4 batteries. So each bank has 4 batteries in series. And the 2 banks are connected in parallel. This delivers 48V. Its connected to a Growatt SPF5000ES and a Victron BMV 702 Battery monitor (with 3 Victron battery balancers) To setup the...

I have a Growatt SPF5000 ES and a Victron BMV-702 battery monitor. The thing is that the Growatt says the battery array (Lead Acid) is at 50%, while at the same time the BMV says that it's still 97% full. I believe the BMV over the Growatt, because when the Growatt reports that the battery...

Hi guys, I have 2 Growatts SPF5000ES in single phase, parallel mode. Everything is connected in parallel, as the documentation explains. One single battery bank is connected to both Growatts, same cable length, etc. Growatt 1 has solar panels directed South Growatt 2 has solar panels directed...
