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 10kW Growatt inverter shuts down every night; presumably because of Low temp. The last recorded temp on Solar Assistant is just below 2.5C I have the batteries on heating pads, but if the Inverter shuts down the power generation I lose the heating pads. I tried connecting the heating pads...

Yes, But not connected and only one is running SA

I am not getting nearer to any sort of understanding of how my Growatt inverter actually works it looks like. If I look at the Screen on my Inverter the settings that should trigger the Dry Contact are #1 SBU #12 40% #13 80% If I look at the Inverter Config Page in Solar Assistant, it shows...

Never "played" with BMS tools, can you assign certain signals to the dry contact in BMS tools?

I'm not sure if I 100% understand the full setup of your system but pumps are pretty simple. You power them with 240V (mostly) (Sure you can use 120V or DC even, but from what I think your setup is, you are going to need 240V) and they pump. I use VEVOR 3HP deep well pumps in a barrel to pump...

I understand the concept of Dry Contacts, it's basically binary code :"OPEN"-0 OR "CLOSED" -1. So with 4 terminals on the server rack battery , you can basically create 16 "messages", or communicate different states. I wonder if somebody knows what these messages are, I assume they are...

Kudos for solving this "problem", before it was an actual problem :) Where is the water from the stored water tank coming from? Are you bringing it in? In that case I understand you went as far as figuring out this 15-minute cap. I have a similar situation, but I am pumping water from a creek...

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 question is easier than the answer. The problem is (in practice) that by only looking at the material you overlook the actual enclosure package. I assume You are probably not going to enclose the front and therein lies the problem. In order to calculate the R value of the enclosure as a...

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)...

The question remains whether Solar Assistant is able to control the dry contact settings. My assumption is that they can write values on all fields/values that can be set in the settings page you see on the US.server page. The Dry contact setting does not seem a value you can set individually...

Thanks, @timselectric, I will look at #19 and #20, but I though they only mattered if a User defined charge profile is chosen in setting #5 and I am on LI. The generator is brand spanking new so doubt that that's the issue, but I'll measure resistance on the two wires next time (If I can even...

#1 SBU #12 40% (LI) #13 80% 2x200AH 48V LiPO battery I realize now that I do not know what value I set for #14 ( Charger source priority: ) Does that need to be set to any specific value for the dry contact to work properly? I was going to check remotely, but I lost power...

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...
