Any recommendation on a dual fuel 2-wire start capable inverter/generator in the 5-7 kW range?

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...

I use this set for everything. https://products.wera.de/en/tools_by_trade_tool_sets_for_bicycles_and_e-bikes_bicycle_set_torque_1.html They are a bit expensive in the US so I just order from a german bike shop (bike components). All the WERA tools are amazing; great quality and good value.

For reference : I run a 3HP 240V deep well pump (vevor) to pump water from a creek to a tank. 1.5" Poly Pipe around 900' in length with 450' head. Have 10kW solar system with growatt 10kW inverter and 2x200AH 48V Lifepo4 powering the whole thing. Works well when pumping but it does feel like I...

Yes, But not connected and only one is running SA

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...

Awesome! thanks for sharing, I'll try this weekend.

That seems like the way to go indeed without spending a lot of $$$ for a new inverter....

Thanks for the great ideas. Just to clarify the receiving remote cabins would all have their own solar and inverters. The distribution line is merely to provide additional charge in case the cabins run low. So a low amp solution is absolutely doable. I did not consider a DC alternative at...

Were you able to get this Connected and working properly? If so please post the resolution. It looks like the 2 wire starter KIT is just a bunch of wires that are easy to make yourself but it would be good to know what to connect where. This is what the instructions say, but without seeing the...

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...

Hi B-Mod, I have looked around for some instructions on how to configure the Growatt inverters via a PC but not really getting good info. Could you share the youtube link if it is not too much trouble? thx!

I have not yet been able to communicate and connect any of my 3 Growatt inverters via the Shine App. Very frustrating software that just keeps going around in circles. If only they made products that were user friendly.... I'm going to try one last time but this Solar Assistant is definitely a...

The cabins are fairly close together 60'-100'

#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...

By the way, for what it is worth. I did just get a "manual" in 50% English that pretty much describes everything as per the Youtube Video. Why this is not properly translated and included as a manual is beyond me, but I have attached it here for reference. In case anybody runs into the same...

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...

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...

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...

Thanks for the ideas. The "problem" with the "6th structure", some kind of central power hub is that it is static. A static infrastructure is great if you know exactly what you are building (which I do not). would love for the network to be agile. you start with 2 cabins and keep adding cabins...

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...

Thanks for the ideas. So basically the advice is to Create one Power hub that feeds a Split phase grid to the individual cabins and the cabins each have there own PV's/ Batteries with ~1/2 reserve. I'll look into the idea of increasing a cabin (site) in the middle somewhere that acts as a...

Thanks for the responses, learned a lot. It does look like the "grid" could use some kind of communication standard. Managing the capacity in a cluster of around 1500 households (which is a good average substation size) with some hybrid of solar and batteries seems somewhat feasible. If data...

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...

Thanks for posting this. I'm designing a system for an off grid cabin with a 10kW Gruwatt Inverter Charger and 20 kwh of Lipo batteries. I think I am going to need to use a generator in winter to charge the batteries (live in WA so sun is a maybe in winter :). I understand the idea of using a...

Digging into this a little more, I fear it may be a bit more complicated. While Generac Generators are two start capable they do not all have this built-in and you need to buy a 2 wire start Kit for $30 or so. It is basically a bunch of wires that need to be installed as per this document...

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...

You can of course generate energy using PV's as well as Solar Thermal; I have no dog in this fight. But a back-of-the-envelope comparison in scale: You would need around 700kW of solar PV which translates to a whooping 1400 panels @500W each.... ~3800m2 (40K SqFt) of solar panels. That is a...

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...

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...
