No worries Matt. I'll hold on to it for now unless another buyer comes along. Good luck with your off grid solar project.

Great. I'm in El Cerrito, CA. Are you nearby? If you want to pick it up, you can text me at 708-925-7482-----Mark

Works great! Barely used in an off-grid set up to charge my plug-in hybrid car. System works so well I decided to upgrade to a 240VAC inverter to so I can use a Level 2 car charger. Unfortunately Giandel doesn't sell a 240VAC model in the U.S. market so I purchased a Sigineer inverter which...

I am very happy with my Giandel 24v to 120ac inverter but now need 240V output. Am considering the Sigineer Power 6000W 48V Pure Sine Wave Inverter. Does anyone have experience with this model or other 240VAC inverters? I would also welcome suggestions for alternative inverters.

I am looking at the following Sungold 24Vdc inverter to accomplish the same 240VAC split phase output. Does anyone have experience with this product? Manual is attached. SUNGOLDPOWER 6000W 24 Vdc Inverter Charger,Peak 18000w,240 Vac Input, 120V/240V AC Output Split Phase,Low Frequency,Pure...

Well, the overvoltage problem with my Renogy charge controller damaged some of my LiFePO4 cells even with a BMS. I ended up getting my money back from Renogy. Replaced it with a Victron charge controller which has worked flawlessly for months now.

What is the make and model of the ATS shown in your setup?

So I ordered the NoFuel transfer switch but immediately returned it for a refund. Though it claims to be able to handle 100A, the contact lugs will accommodate wires no larger than 10AWG.

I'm interested in your DIY transfer switch. Can you share details about it?

I have had two of those JITA 12.8V 300ah batteries connected in series for several months now. So far working great! Using them to charge my plug-in hybrid car and provide back-up power for my house. Have a Victron charge controller and a 24V Giandel 4000/8000 inverter

Solar enthusiast, thanks for your informative comments and for the links to the videos. I think I will go ahead and order the NOFUEL ATS and try it out. I don't need frequent switching but am still a bit concerned about the backfeed issue. Is there any way to test the isolation?

Solar Enthusiast, thx! Can you share the link for the YouTube video of the teardown? I haven't been able to find it by searching YT.

Does anyone have experience with NOFUEL automatic transfer switches. Here is the one I am considering: https://www.nofuelpower.com/pv-solar-automatic-transfer-switch-3p-100a-220v-solar-to-grid-dual-power-5060hz.html I have attached the manual. I am running an off-grid solar setup with a 24V...

Can anyone suggest a good 100 amp ATS that is actually available? I settled on either a Cummins RA122N3 or Generac RXSC100A3 both seem to have lead times of 16 - 20 weeks.

Thanks, Tecnodave! I am glad to hear that it is possible to connect the load output of the inverter to BOTH L1 and L2 inputs on the transfer switch. The only 240v appliance we have is a dryer which we obviously wouldn't use during a power outage. Are you familiar with this Cummins 100A...

TechnoDave,thanks for your explanation. I still have a question on connecting the 120VAC output of my inverter to a transfer switch. Inverter supplies only one load output lug not L1 and L2. Can the inverter load output be connected to EITHER L1 or L2 on the transfer switch?? That would...

Would this be an alternative? Progressive Dynamics PD52V 5200 Series Automatic Transfer Switch - 240 VAC, 50 Amp https://www.amazon.com/Progressive-Dynamics-PD52V-Automatic-Transfer/dp/B003VAWNVK/ref=cm_cr_arp_d_pl_foot_top?ie=UTF8 It does appear to have L1 and L2 inputs. Unfortunately it...

James, I have the same question regarding use of the MOES Dual Power Automatic Transfer Switch but am unclear from the responses to this thread if the answer is clear. I would like to run the output of the transfer switch directly to my (small) house electrical panel but don't see from the...

Sunshine Eggo, thanks for the heads up re/ the charge controller. I was a total newbie when I bought the set-up from Cutting Edge. Really unethical that they are STILL selling this product and advertising it as MPPT technology. As I mentioned I have changed over to a 24V system with a Victron...

Bud, I am in the S.F. Bay Area (East Bay: El Cerrito).

Purchased less than 1 year ago. Works great but I am now upgrading to a 24 volt system. Just needs 12V battery and solar panel(s) and/or wind turbine. Will sell for $700 or best offer. This is what is included showing price I paid: CEP Trailblazer Complete Premium MPPT Solar/Wind Generator...

Bud, yes that is the correct model. Alice thanks for your response. Glad to hear that it has an AC terminal block and that your friend has had a good experience with this Giandel inverter.

I am considering purchasing the Giandel 4000W 24 Volt Heavy Duty Pure Sine Wave inverter. The only AC outputs I see are four 120V outlets. I want to connect it to a Reliance Control transfer switch. Assuming that is possible, how would I make the connection??? Would I use one of the AC outlets...

So I purchased two of these and have had them running for two weeks. So far they seem exactly as advertised. Obviously I haven't taken them apart. Also haven't done an accurate capacity test but they seem to deliver approximately 600Ah (two batteries are connected in parallel),

Charge controller is manually set to 12V. Not sure what you mean by Batteries Equalization function. "Equalize Charge Volt (V)" is set to 14.4V. I do notice that "High Voltage Disconnect" is set 16.0 V which seems way too high. Also "Charge Limit Voltage" is set to 15.5V and that also seems...

Renogy Rover 100 charge controller periodically sounds a "battery over-voltage" alarm. While the alarm is sounding, the Renogy BT app displays voltages as high as 17V (for a 12V LiFePO4 battery) and I get the same reading when I use a voltmeter on the battery terminals. But after a few...

Well, I went ahead and ordered two of them (300Ah) and they are due to arrive today. I don't plan to tear them apart but will let you and others know if they perform as advertised.

Definitely were never put in a hot environment.

Here is how they were wired up. Yes those 4 wires are on the main negative terminal? Thanks. Bus bars were stacked correctly (not top on one to bottom on next). Is it too late to compress the cells and replace bus bars with holes not slots? Is it likely that the cells are now fried?

Does anyone have experienc with this battery from Amazon?: https://www.amazon.com/JITA-12V-300Ah-Lithium-Battery/dp/B092326XK8/ref=cm_cr_arp_d_product_top?ie=UTF8 I don't know if I can trust Amazon ratings but in this case they are quite high.

I purchased 4PCS LiitoKala 3.2V 280Ah lifepo4 battery DIY 12V 280AH rechargeable battery pack for E-scooter RV Solar Energy storage system x2 from Ali Express. Took over 2 months for them to arrive. Configured them in a 12V 4s 2p arrangement with a Daly BMS and am using a Renogy 100 charge...

I have a Sungold 12v 4000w Pure Sinewave inverter set up and connected to a 12V-560Ah LiFePO4 battery bank that is fully charged to 14.6v. AC 110V output works when I test it with a 1000W hair dryer but the inverter beeps once (red alarm LED turns on briefly) and shuts off when I attempt to...

I need to mount six solar panels on a steep tile roof. Since I do not want to make any holes in the tiles, I am making a DIY version of the Z-Rack system (my job is too small for them). At this point due to a knee injury I am not able to get up on the roof myself though I can supervise the...

I plan to run a 24V system with two SOK 12V 206AH batteries connected in series. Looking for a reliable charge / discharge monitor that displays % charge level of batteries, battery voltage, available Wh, solar input charge rate (amps), and output load (amps). Anyone familiar with this monitor...
