A better question is "What are the manufacturer's charging specs for the battery?". I have used AGMs for 12 years. Stop focusing on various charger's specs and post the battery's specs and then myself or others will be able to advise. Just as a guess, you will be using custom. You might be...

Welcome to a new member! This is a DIY project, not a pre-packaged commercial software with a free-to-try clause attached. It needs a good level of programming experience to install and use. Do you have the MODBUS document for your GW? Would you be comfortable installing this free as in...

That would be the setting #1 called 'Output Source Setting = SBU on my Growatt 3000. SBU is short for Solar, Battery, Utility. In English that says If Solar cannot support the loads, assist with Battery, otherwise bypass the inverter and transfer all loads to the Utility connection.

Are PMs searchable?

Part II. Test 3. Is there a separate cut-in/cut-out for non-resistive loads? This morning I tested the inverter/charger(I/C) in the trailer and it would not start with power save on. It has a 12V, 50A charger which could pull 1000W on startup on a low battery. With the battery at 12.5V...

Calculate W/m^2 using 150W and dimensions 38.8*38.8*1.2inch (98.5*98.5*3 cm): 150 / (.985*.985) = 154.6 I have 200W panels measuring 39in^ which converts to .9906m 200 / (.9906*.9906) = 203.8 The 150W is 50W worse per m^2

There is no 'dry contact signal switch' on my GW, nor is there a program 24.

Has anyone had any experience or problems reconnecting after a BMS disconnect?

I am only saying that the three light circuit tester showed only one yellow light indicating a 'no ground' fault. I have no idea about the case. I don't know anything concerning this comment or whether or what is a good thing or a bad thing related to my Growatt. If it is important that I...

I prepared a reply earlier but it seems to be missing. I'll try again, but this time I will retain a copy. 1. The entire microwave(MW) is off, not just the clock. When the GW pulses, the MW beeps. The MW cannot make the power Saving Mode(PSM) switch off because the MW draws less that...

I am betting charging works like this that I posted recently:

Take a look at the quoted text below. It was copied from page 18 of the Meanwell pdf. I bolded two passages that seem contradictory. Begin quote: This product is a built-in battery charger and is planned to be installed in caravans and other similar vehicles. This product can charge at least...

I posted pics of this BMS here.

Perhaps Growatt is the one that is finally doing grounding right after all. That is exactly what my Yamaha inverter genny has done since 2013. Perhaps Yamaha has had it right all along as well. I had to learn to use the NGB plug quite some time ago. I did use an inverter/charger with the...

Three 440s will likely exceed the Growatt's 145VOC limit. I have a 410 and the VOC is 49.

I guess because it has the word induction in the name. It is not a resistive load.

Post a link to the battery specs and someone will read them for you and then answer your question.

I will be using power from the LFP to charge the AGM. I will explain why that is a good idea that needs no excuse as if I have done something wrong. A few days ago while rolling this around in my head, I wrote up how I plan to add LFP to AGM. Here it is: If this is true, there will be a...

Batteries don't have feelings!

What happened to the 24v DIY system...........................

I'm glad you cleared that up. I thought SLA meant maintenance free, where you seal up the acid in a sloshy. So what do you have? I have Eaton Powerware AGM. Eaton is a NYSE(symbol ETN) listed worldwide turn-key power management company. The only specs printed on the case are 'Float 13.5 -...

That is correct. I have the same 24V GW as yours. P10=2 cannot be changed. I suspect that a 48V model would be factory set to 4 and also not be changeable.

Battleborn, and other lithium packs, tolerates the improper Lead-Acid charging regimen by employing a BMS to protect the cells from such foolishness as temp-comp, bulk, absorption, float, boost, storage, and equalize. I have ordered my first lifepo cells and I will bid good riddance to that LA...

No. The Growatt does not shut down but works exactly as it should when transitioning in and out of power saving mode. The I/C has a 15 second pause while it validates the quality of the Growatt's 120VAC. On power saving mode the Growat emits a brief pulse to see if anything wants to use...
