I did a chat with Giandel and asked why they ship their 12V/1200W inverter with 5 AWG cables....They told me itwas tested, and if properly tighten, they are all good being only 2 ft long Very surprising...........and dangerous it seems !!!

Would it be "safe" to use 2 AWG wires with the 12V/1200W Giandel inverter, knowing it won't be running continuously (the sump pump usually kicks in every 10min for ~30sec in the worst case scenario)? And in that case, what fuse should I use? Or are 2/0 AWG definitely required? And by the way...

For their 12V/110V 1200W, Victron specifies 2 AWG on the manual....

So to be safe, I should go with 2 AWG.....But not 2/0, right?

Once the inverter's remote is activated by the sump pump switch......will it always stays ON?

Nice file......thank you for creating it and sharing it The Giandel pure sine wave 1200W is apparently cheaper on the Giandel site than on Amazon.......

When I put 12vdc, 120A and 3 feet, I get 4 AWG 4 AWG is the recommendation up to 160A For 165A, it shows 2 AWG So...................2/0 seems huge. Am I missing something?

Any idea why Giandel includes a 6 AWG set of wires? It's also the size they specify in their manual .....! I understand the math you provided, but if 2/0 is what I should use, it seems very weird the manufacturer talks about 6 AWG

Yes, but when the pump kicks in, the sensor will re-open quickly, and the pump will run on a timer

From the link in your previous answer, the Giandel PS-1200JCR Pure Sine seems a good choice with low consumption at idle Will 4 AWG wires be ok?

What would trigger that switch though?

What would be your recommendation for a decent 12V inverter in the 1,200W range (to power a sump pump) that has a low power consumption at idle? Thanks

Hello Assuming I have 2 x 12V batteries (A and B) that are different types and I don't want to have them in parallel (One is a new 100Ah LFP and the other one is an "older" 75Ah AGM but in good shape) Is there an module or circuit that would automatically switch from A to B when A has reached a...

How are you wiring the 3 batteries in parallel? I see 2 fuses......and how does the smart battery sense work exactly?

Hello, Is there any good tutorial to build a portable power station using 12V 100Ah mini batteries Redodo or Power Queen for example)? Could be 12V (2p) or 24V (2s2p) and will use the proper inverter accordingly Not sure what configuration would fit in such cases by the way...

Hello I'm retrofitting some old solar garden lights to make them run out of 6VDC (2 leds in // and 47 Ohm resistors) Each lamp will draw ~0.75 Watts and I'm planning to have 10, so 7.5Wh But.....I don't want to run a 100 yard wire, bury it, etc... So I was thinking to have a LiFePO4 12V battery...

A 12.8V 100Ah Redodo LiFePO4 battery for $235 shipped.......is it a good deal?

Has anyone tried the new Redodo power inverters (1000W and 2000W)?

Is there any good tutorial you could recommend? And about the cells to buy, can you provide a link? I looked at the Qishou website, but redirect to Alibaba?

Assuming I don't want to have the charger (Victron 12V/15A) permanently wired to the battery LFP 12V 100Ah), what type of battery disconnect/switch could I use? Would a 110V 2 pole switch work? If not, what are your suggestions? FYI, the positive wire is protected by an inline fuse.....

Would this be a good choice (I like the possibility to manually switch the circuit) https://www.amazon.com/YOUNG-MARINE-Circuit-Trolling-Mount-50A/dp/B075KZTKDD or this: https://www.amazon.com/gp/product/B08ZXNZ3D3 with this: https://www.amazon.com/Conext-Link-AFS25-10-Nickel-Fuse/dp/B01D9ISXW6

The pump's specs says 10A continuous and 18A in-rush...

is 12 AWG enough?

About the wiring, should it be A or B?

Correct....not in conduit Any fuse holder suggestions with screw terminals?

I'm not using an inverter nor pv..it's for a 12VDC backup sump pump So I need a charger that will maintain it in storage mode. Thinking about the Victron IP22 12V / 15A It doesn't come with wires, so I'm planning to use 10 AWG.... And I was asking for the fuse / fuse holder type. I know the fuse...

Yes, this is why I mentioned the Victron... What about the wire size and fuse holder type?

I think the 15A version does not.....

Assuming I buy the Victron IP22 12v / 15A, it doesn't come with wires, so I will have to get some 1) I assume 10AWG are plenty enough for 15A? 2) I need to install a fuse, and it must be as close as possible to the positive battery terminal, correct? 3) What type of fuse / fuse holder should I...

So better go with a Victron charger, right?

Hello, Other than Victron, what chargers have a storage function (to maintain the battery at a reduced voltage once fully charged) About Victron: other than the IP (22 vs 67 and the 15A vs 17A), are there any major differences between...

So it means 1/0 AWG + 125A would be.................just fine?

Ok for the MRBF fuse...how many amps should I get for a 2/0 AWG ?

Thanks for the Windynation link So better go with something like that for the fuse...

Assuming I go with a 1000W or 1200W inverter, and get the 2/0 AWG Harbor Freight cables: https://www.harborfreight.com/3-ft-20-awg-inverter-cable-set-63748.html Am I good with a breaker like this one: https://www.amazon.com/dp/B0BK327G4D/ref=twister_B0B2RM3TPF?_encoding=UTF8&th=1 Should I go...
