I am looking for an Electrical water heater. Just need it for a shower so 20 Gallon or even less would be OK. I am powering it from a 10kW Growatt SPF with 2x200ah 48V LiPo batteries. I don't think I need quick recovery time per se. Would it be better to go for a 240V option or would a 100V...

My Sunpal 48V 200ah Batteries use a PACE BMS that has 4 dry contact ports on the front. I have seen them on a lot of server rack batteries. I have never used these contacts (I use the CAN connection to the inverter and the RS232 to connect to Solar Assistant) but I'm curious. I have tried to...

The settings in the Growatt inverters can be changed manually by changing the values of the 28 menu options on the touchscreen. They can also be changed remotely by logging into the server (https://server-us.growatt.com/index) and accessing the settings via the wifi datalogger (if installed)...

I just Installed SA 2 days ago and love the interface and the functionality. Not going back to the Growatt server page or Shine anytime soon. I have a question. It looks like Solar Assitant can change a lot of settings in the Inverter, but is there a way to get SA to open and close the Dry...

Strange question maybe. How do you know what make and model of BMS is installed in your LiFePo battery? I have a couple of "Sunpal" 48V 200ah batteries that I somehow ended up owning (long story). They work well but I have no idea what BMS systems are installed in them. Is there a way to find out?

Grid Forming Inverters are being suggested as a solution for the Solar and wind "supply/demand" problem. https://www.sciencenews.org/article/one-device-transform-power-electical-grid-inverter I will admit that I do not really not what the difference is between "grid following" and "grid...

Hi, I had 2 Growatt (SPF10.000) inverters report fault 4 this morning. SOC on the 2x200AH 48V batteries was >40% but the temperature was quite low. Around 6 degrees C ( 42F) so my guess is that the Battery BMS is going protective because of low temp but not sure. Has this happened to anybody...

Hi, Any recommendations on a generator to pair with a Growatt 10KT dvm inverter and 2x48V Lifepo 200Ah batteries? I Have a cheap WEN 10kW generator I use manually but would like to see if I can use the dry contact functionality on the inverter to activate the generator automatically. Something...

Question: I currently have 3 Growatt SPF10.000's to power a couple of off-the-grid cabins. The inverters work fine, but the do produce an awful lot of noise when the load exceeds 1kW or so. The inverters are in there own little room but its still pretty audible and annoying. My guess is 65dB...

Electrical question. I have a situation in our off-the-grid cabin where the distance between the 10kW Solar/Inverter/30KWh batteries and the load is rather long. The distance is over 1000ft and maybe even longer (2000ft) for a future extension. For a 50A line, his would mean really thick...

Hi, I could use some advice for a system that has multiple buildings (cabins) and is 100% off the Grid. I am thinking about 1 main building with 20 panels and 40kWh Batteries and 2 smaller cabins with 10 panels and 10kWh each. Can I use the Inverter in the main building to "create a Grid" that...

I am looking for some help in designing an off grid system for 5 off the grid Cabins. All the Cabins will individually have 10kW solar with an 10kW Growatt inverter and LifePo4 20kWh battery storage. I was wondering if it would be possible to "network" the cabins, so that they would share...
