I am looking at putting a Low Voltage Disconnect between my battery BMS and Giandel Inverter, as I don’t trust the Inverter’s LVD. 24v system, needs to be a 200A - 300A LVD and I would like to be able to adjust it. Any suggestions?

Are Samsung EV Lithium Ion 12s 44.4v a good options for building a 48v small off grid system? I am thinking of using maybe 6 or 8 in parallel for a cabin. Or are LFP still better?

I’m looking for a breaker for 120v AC to use after my 4,000w (6,000w surge) Giandel Inverter. It will go between my inverter and main breaker panel. My inverter is about 40’ from my main panel. What do you all use for this situation

Do I need to put a breaker inline between my Giandel 4,000w inverter and my AC service breaker panel in the house? Or does the Inverter already have one internally? (Offgrid) Inverter will be supplying the AC panel in the house, and I'd like to run it thru the top of the 200A panel. (I...

Hi, I am using Renogy Rover 40A MPPT. However this SCC is not disconnecting when the LFP batteries reach high voltage.The BMS keeps shutting down due to high voltage however I would like the SCC to shut off before the voltage reaches BMS HVD. (Using 2p8s 24v Chargery BMS8T-300 BMS,) I set...

Is there a way to take two 110v lines and make one of them 180°out of phase to make 220v split phase?

Is this going to be praise enough for Lithium battery systems? (Measures AC current only)[edited]

So I've done some reading other posts on the topic and it looks like most every thread people are bemoaning how their torque wrench stripped of the bolt before it reached the specified torque... it seems like I could just do it by hand at that rate or do I need to buy a wrench that's $$$ more...

I'm planning to use them to connect my inverter and CC to my 300A Chargery BMS (LiFeP04 24v system) Or are there other options anyone would like to recommend?

I am planning to run a cable from my 4,000w (Peak 6k) 24v Giandel Inverter to my 200A Breaker Panel (Off Grid) (I am wiring it in as 120v AC). Doing some research on size of wire needed for this and not getting 2 numbers the same (I guess differences in permitted voltage drop etc) What do you...

I am planning to run 2x 40A Renogy Solar Charge Controllers into my 24v LFP Battery Bank (using 10AWG wire). I want to fuse between SCC and Battery. Is this a good option; what are other people using successfully? 2 Piece 40A 40 Amp Circuit Breaker with Manual Reset Fuse Holder for Car Audio...

Would there be a problem connecting a 12v 200AH Lithium (Mobi) Battery in parallel or series to a 12v 206 AH (SOK) battery?

I'm planning to order either 16 or 32 Eve cells (280AH) from @Amy Wan (Luyuan) to build a 24v system to be charged with Solar. Would it be okay to go with the 32 cells, or is that too many parallels/series connections? I heard @Will Prowse say something about a recommended max number of...

I followed Will's link to his supplier on Aliexpress - https://www.mobile-solarpower.com/raw-lifepo4-deals-page.html For 16 cells it ends up being $2,505 delivered here in Canada. (About $2,702 USD) Does this look like a good deal?

How important is this? I'm planning to connect a 4000w inverter to a 24v battery, if I need it how do I choose a resistor? [Post edited]

Looking to purchase some solar panels, 4x 275W and several 100W, in lower BC (Kootenays) let me know if you have any suggestions. Thanks

Planning to build a 12v battery for my current system ( I am using 1 SOK battery 206AH but thinking of adding it to the new one I build or replacing it with a larger one built from LiFePO cells myself) Open to recommendations on the configuration, I am thinking to go with 16 cells -(My first...

If I wire 2x 12v SOK batteries in parallel does my max amp discharge change? SOK max discharge is 100A, would I get 200A or nearly that?

A 24v battery would need to have 2x the amp hour as a 12v battery in order to have the same amp hours as a 12v battery, in that case would it not be better to make a 12v battery? I am aware of the difference in wire prices etc, I already have a 12v Giandel 2,200W inverter and the cost of buying...

Hi, I am looking to set up a system to pump water from my well using a 220v ( about 6.5a) water pump (400' + deep) I have 6x100w panels and a 206ah SOK Battery and have ordered another 200ah battery... I would like suggestions on a 12v or 24v inverter to use for this. I am thinking it would be...
