No proof Chins are B, so stop.

Yeah, Chins seems like a deal! I'd build my own before buying SOK. I may still buy 1 or 2 Chins and test / see how long they last / warranty issues.

Don't have tools to balance. At $499 / 280 ah, do you even want to bother? Cells plus shipping / BMS and tools will easily be over $499. Even if you purchased multiple batteries, the cost seems minor over the cost of building. Just asking for the average person that's not looking to buy tools...

You can buy a Chins 280 ah battery with BMS for $499 (free shipping) on Amazon. Versus 290 ah cells for $410 (plus shipping) and need to add BMS and balance. Opinions??? https://www.amazon.com/LiFePO4-Battery-2000-5000-battery-Off-Grid/dp/B0C47FJZFZ

Yeah, will be getting a jumper. The charger has 2A, 4A, and 8A settings. I changed all my lights out to low-watt LED. Which reduced consumption 50+ watts, so 4A shouldn't be an issue. I think it will work at 8A. Guess I'll find out. If 8A is too much, I could buy 2 of them and run one at 4A and...

The charger has 2A, 4A, and 8A settings. I changed all my lights out to low-watt LED. Which reduced it 50+ watts.

It says it stops charging once full. I'll probably add one just to be safe. I'll carry a jumper just to be safe as well.

Batteryhookup just came out with 30Ah battery. I'm going to buy 2 for $147 and hook up in parallel and have 60 Ah for the same weight as most 50 Ah batteries (11.5 pounds).

Are you talking about a switch to cut off the main battery from the alternate battery?

Run 12v devices when the motorcycle is off when stealth camping. It's a dual-sport.

Yes, just to run 12v devices when the motorcycle is off. Use when stealth camping. I hear ya. Use to own a Ninja 600 / GSXR 750. It's dual-sport, so it doesn't matter. A bigger alternator (stator) doesn't exist for it. Believe me, I've looked.

I'm going to buy a 50Ah battery (probably LiTime) to put on my motorcycle. I found this 8A DC to DC charger, which I can run off my bike. https://powerwerx.com/dcdc-charger-lifepo4-8a-adjustable Do I need to buy anything else? I just need to run 12v devices.

Yea, I was really skeptical. That's so cool. Is this the correct affiliate link for you? https://www.signaturesolar.us/collections/24v-battery-chargers?ref=cPwLcVc0SW-BjN

I watched Will's video on signature solar rack batteries and saw they had chargers. They claim to be 95% efficient. While I haven't looked in a while. I don't know of any chargers that are that efficient. Does anyone have their 24V / 40A charger and can confirm it's really that efficient?

sure, no problem.

Your power usage isn't going to be static with a mini-split. Once your set temp is reached it should use much less. However, the size of your rig, how well it's insulated, and the outside temp will all affect it. EER if I recall correctly is based on 95F / 50% humidity test conditions.

@aangel Here is a video worth watching.

You want to use EER, not the SEER. EER (energy efficiency ratio) is a cooling only ratio. SEER (seasonal energy efficiency ratio) is a cooling and heating ratio.

That is why I asked if the higher Vmp of putting panels all in series VS efficiency of SCC be slightly better with the lower Vmp of 2s2p ... which would be better in the long run.

The panels are 24.3 Voc each. So 2s2p is 48.6

Based on that. I could do 2s2p (40.8 Vmp / 48.6 Voc) and go with the 100/35 controller. However, if I need 24v + 5v for the SCC to start. Wouldn't the higher Vmp (all series) be better?

My bad, I will have a 24v battery bank. I just don't see having a choice but to go with the 150/35 due to Voc and the difference in price isn't that big of a deal. The second set of panels that I would put in all series are a good deal. But they are on sale only till tomorrow. The first panels...

The Victron 150/35 SCC manual says +5v over battery bank and MPPT range 30V to 130V If I go with the 150/35 SCC, Voc shouldn't ever be an issue. The efficiency of SCC vs. voltage, I have no clue.

When you say 80% of max. Are you talking Vmp or Voc? Here is what I'm struggling with. Specs for (4) 200w panels. Maximum Power(Pmax): 200W Maximum Power Voltage(Vmp): 37.6V Maximum Power Current(Imp): 5.36A Open Circuit Voltage(Voc): 45.4V Short Circuit Current(Isc): 5.83A I could do 2s2p...

I heard that your solar panel voltage should be at least 20v over your battery bank voltage. I assume that this is because the higher the panel voltage the less sun it will take to get power in and get above the battery bank voltage so your charge controller starts charging. So they start...

None of the panels I'm looking at list a Pmax/Voc temperature coefficient. I couldn't find anything in the victron 100/30 manual that says anything other than the max voltage is 100.

I found a good deal on 200w panels. $606 for 4. Specs Maximum Power Voltage(Vmp): 20.4V Maximum Power Current(Imp): 9.80A Open Circuit Voltage(Voc): 24.3V Short Circuit Current(Isc): 10.2A I'll be using (8) 280ah cells configured as a 24V battery. I've heard you want your PV voltage to be at...

Did you end up purchasing? I was originally considering getting (2) trina 410 watt panels and making a rack for my SUV where the bottom panel would slide out and both panels tilt. I'm now thinking of getting (4) of the 200 watt / 24 volt rich solar panels. There slightly larger than what I...

What is the consensus on the quality of Rich Solar 200 watt panels? Is there a better brand you would recommend? I have limited space and I need to get the most out of it. I can mount (4) 200w panels on the roof of my SUV with a slight overhang. I can mount an additional 2 panels stacked...

I have a Frigidaire FFRE0533S1 5000 BTU window unit. It has a low-power start-up and is nothing like that. Someone from Frigidaire commented on a question about this and I remember them saying it pulled like 525 watts. It was definitely in the 500's. I don't have a meter that will read the...

It's not bad. I think it's like 525 ish.

I'm looking to run a 410 watt AC as part of the test

I actually do plan on buying one to use with my generator if needed. Can you hook one up in place of a battery bank?

I'm going to get (8 ) 280ah and set up as 24v. So the inverter will be 24v. While waiting, what if I was to just get a pair of 12v (probably starter batteries that aren't holding a charge very well anymore) and set up as 24v. Would that suffice as a means to just test?

I haven't purchased anything yet because I'm not sure if I should wait until I have all the cells first. 99.9% sure I'm going to get (4) rich solar 200w 24v panels instead of the (2) trina 410 panels. The (4) 200w panels will cost about double the (2) 410w panels. $880 VS $442. However, the...
