Its not just a couple of pizzas. Its $100-300 saved on the MPPT charger. $30-50 on the wiring $100 for a BMS

You really should try to use the plastic signboard / cardboard. I have them under my flexible solar panels and it makes a world of difference. I cut the signboard to size, used silka flex to attatch the signboard to the panels. Then I used a 2 inch wide 3m VHB and taped the top of the panel...

The unfortunate thing about a lot of chinese resellers if they will start off on the straight and narrow. The cells will be genuine grade A. But then they will start to slip once a customer base is established. They will send a batch of grade B or A- and hope no one notices. I know there is...

The minisplit i'm looking at is an inverter style, so its soft start by nature. Pulls 700 watts on average when running. I'd expect to run it for 4-6 hours during peak sun and to be offset by the panels, so 4.2 kwhrs. The fridge will pull around .2 to .5 kwhrs. The rest of the loads will be...

My flexible solar panels were literally 1/8 of an inch thick, super thin plastic that you can roll up into a tube if you wanted. If you pick them up they droop like crazy. Pretty sure I broke a few cells as I heard a few crunches while taking them out of the box. From what I read, black panels...

Thats great advice. How do you use 4-6 kwhrs in the winter? I'm thinking 200ah won't be enough to run the a/c much. But for the non summer months it would be more than enough for a fridge and some fans.

That's true, but the cells don't expand that much and I doubt the compression would get beyond 15-18 psi (which is the higher end of the recommended compression)

Wow that seems really bad to me, but that is a huge cabin sized one. 12 watts idle I can handle. 25 watts too. It just sucks to lose 12-24 amp hours while the thing idles over night.

Its best to buy a universal set of adapters and most EU stations can't fill a US propane tank.

Dang that's thin. Be Careful handling them, I left mine inside of the cardboard boxes because they are so floppy. I bought my flexible panels with the expectation they will only last 2-5 years at the longest. Its nice for my van setup or non flat roofs, but damn those panels do not age well.

You can parallel and series wire the panels depending on the MPPT and panels. Damage to the inverter is caused by heat. If you run a 1500 watt load on a 2k watt inverter and its in a small box with no airflow, your inverter will die quick. If you run a 3k watt inverter with a 1500 watt load...

I've seen a killawatt meter used on some different mini split units. The 6000-8000 BTU units use arund 600-700 watts of power. The 9-10k BTU units use around 900 watts. A 12k btu will use around 1100. The SEER rating will affect those numbers, higher the better. If you've got a good sun spot...

I have 8, 290ah Eve lifep04 cells in a 24v pack with a jbd bms. I use a mpp solar 24lv unit with 1200 watts of solar. I changed my charge controller settings to 27.4 float and cv as it was limiting my solar input. I went from 400 watts to 900 watts when charging. however, my batteries are...

I want to use a 300 watt inverter for my fridge that will be on 24/7. And cycle the 2400 watt inverter so it doesn't waste 50w/hr idling. I'll probably just install 2 switches. That way I can turn one inverter off before turning the other one on.

My rig has a volt reading which isn't super accurate. Full batteries are 12.9 and it settles down to 12.8. 75% discharge (half of the usable power) is at 12.4v. 50% discharge is at 12v. It will drop down to 11.6 under load but then it rises back to 12 to 12.4 after. Voltage doesn't tell the...

If they are already swollen, compressing them is not a good idea. Compressing them can cause an internal short. Use some flexible bus bars and leave them lightly wrapped with tape or something stretchy.

Thank you for doing that!

Thats what I'm thinking of doing too. Over compression is bad. So even if the foam gives and doesn't provide a solid wall, it will provide a scaleable PSI. EG it starts are 11 @ 50% charge. Gets up to 18 psi at full charge and drops down to a few psi when discharged. Seems good enough

There was an eve testing graph that showed you could get up to 12-14k cycles with around 11-13 psi. I don't have the link handy but it was posted in one of the compression mega threads

So shipping isn't included in the all in one pricing?

Have an old MPP (or similar brand) LV2424, 24v, 2.4kw 110vac inverter, 80a mppt system (or something close) sitting around that you've been meaning to sell? Sell it to me!

I use automatic reset circuit breakers in my setup as its pretty hard to reach.

I've read a lot of threads and it seems that Amy and Michael are the best options. But its tempting to order from one of the cheaper vendors to save a few hundred. Any cheap but good options out there for 280ah Eve cells? Are 280ah Lishen cells a good option? Those go for like half the price...

Its from the MPP Solar official alibaba store. They also sell this one (and a bunch more) which appears to be the exact same 24v model Will reviewed. The one I linked originally has a 105v 40a mppt and a 25a battery charger vs the one just above is 150v 80a mppt with a 60a. The cheap one also...

I won't need much for 12v. Water pump, lights and usb will be it. If I did 24v I would use a buck converter. I'm not sure I fully understand solar charge controller ratings. Its usually voltage / charger output current right? So I could use 2, 100/50 chargers

The only tilt system worth using is one that you can reach from the ground or push a button. Tilting a 300watt panel ontop of a minivan, sure thats easy. Climbing on top of a van/truck and trying to lift 4 panels, not so much. I think a scizzor lift tilt system or some kind of automated jack...

I like this wire gauge calculator http://wiresizecalculator.net/

When I look at this data sheet is says I would need a 100/50 charger to have 1200(1400) watts of solar. Would a 20amp work?

Cancel your order and buy from a supplier who still has N cells. Or make an 8s 24v pack with its own BMS and parallel the two battery packs.

But 2 of them would do it for op 150 amp is plenty for my 24v system
