Three 415W panels mounted on a 2007 Ford Econoline E250. Getting ready for the mini split on the rear bumper.

The light bulb worked. All batteries are under 3.65 volts.

Summer of 2023, hottest year ever recorded in history. I'm running a Sennville LETO 9,000 BTU A/C and Heater off of 560Ah battery and three solar panels mounted on ladder racks on my Ford E-250 van. The mini-split is mounted on the left rear bumper (facing the rear). Batteries appear to stay...

You guys are smart! That is some good information. I will check the system for heat, loose connections, etc. One symptom I'm getting that I noticed was not there before I tried using the air conditioner is the numbers in the Bayite meter attached to a shunt to measure volts, amps, power, and...

I think you're right and 1/0 awg from the old build would be enough. Thank you for the chart.

Dzi, I pulled the trigger on an inverter charger, Samlex EVO-2224 2200W Pure Sine Inverter/Charger, Samlex EVO-RC Remote Control, and 175A Class T Fuse Kit from Don Rowe. They matched the Anchor Express price for the inverter charger and remote control. The solar panels are coming, the book is...

This 20 Amp Commercial Grade Combo Single Pole Switch and Receptacle, Leviton 5335, is the closest I have found so far. The mini-split is 110/120 v only.

These guys are in my backyard, Chesapeake, VA. Are either of these unit compatible with a 24v system? I haven't found a mini split online yet. https://www.hotspotenergy.com/solar-air-conditioner/HotSpot-ACDC12C.pdf https://www.hotspotenergy.com/DC-air-conditioner/Specs-DC48.pdf or this...

It is the Tracer4215BN model.

I communicated with Matt Angelo at Hotspot and he said, "It is a stretch to install one of these AC units on a 40 ft RV, not a realistic option for a van." So, I'm back to the units I was looking at online trying to find one with a high SEER value, and a light compressor unit that would fit on...

Putting a battery together and got some sparks for no known reason. I put my multi meter on the negative pole and my positive lead on the square QR code on top the battery. It tested 3.49 volts. Is this a defect or something common?

Install a mini-split is my advice. The batteries will love you for it.

Add me to the list of people on this forum screwed by Alex Chen and Gloria Luo and whoever is selling them locally in the U.S. I got (I hope) 15 good cells and 1 bad cell. When I asked all three individuals about the bad cell they claimed it was "ov", stored too long, not following Gloria's...

Thanks.

About the cheapest mini split is around $700 for a heater and an air conditioner; that would be a 9,000 BTU model. I am installing one on the bumper of my Ford E-250 van very soon. Was surprised at how much it weighs; just hope my bumper can hold it. Could probably get by with a 5,000 BTU if...

All's well that ends well. I didn't find traces of copper. I covered the QR Code next to the blue "window" area with Kapton tape to insulate the cell casing from any stray electricity and patched a few dings with rubber cement and Kapton tape. Covered the bottom of a couple of cells with...

BB did not send a manual but the flyer is good enough to answer my question and explain the warranty. You are correct; low voltage < 10v. If an individual cell falls below a prescribed threshold, the BMS will prevent further discharge . . . " Like this voltage drop calculator...

Every cell I've tested is leaking through at the QR code. Seems strange that I never noticed it before. The blue outside of the case doesn't move at all but some dings and all the QR codes are hot.

My bad experience turned into a good experience. Amy Zheng is shipping my one cell from Houston to Virginia Beach at her expense. That is real customer service. Highly recommend her for you battery needs.

What is the best way to connect the battery positive and battery negative terminals (BC0 and BC8) on the cells to the BMS and the + bus bar? I want to bend the copper bus bars to 90 degrees, run a 3/8" stainless bolt through the wooden compression wall for the bus bars for battery positive and...

Very significant progress in understanding and work being accomplished due to your posts. Thanks for this help!

All the BS is done. Now, its time to drive to California. I want to thank all of the people who helped me with this project. I apologize for some of the comments I made in this thread. This project, a Ford E250, with four solar panels on the roof, was a learning experience. It produces...

I am modeling my battery after the 8S 24V block setup except I will have two 8S blocks in two steel boxes with two 8S 24V 100A OverKill BMS's. I'm hoping to create a 8S2P configuration. I'm not sure how to wire the two boxes together. If you wire up two 8S packs, each with their own BMS how...

The Samlex EVO-2224 arrived today. It weighs 65 lbs. I can barely lift it. This is for my conversion van solar project. This was $1200. I hope it works.

You're on the right track. I've had a lot of experience with high interior van temperatures. I have 400w of solar, a 30A SCC, and two BB batteries in series in a Ford E250 van. If the sun is shining the temperature inside the van will be in the 90's or higher. Cracking the windows will not...

Looks good. The company that sells it also makes it but they don't have any in stock. I think there is a one week lead time. Lowes has the Southwire12/2 x 8 ft. Stranded CU MC in stock. Most likely their work force is doing something other than making these boxes and it will be 2-3 weeks to...

Can panel wires vary in length?

The batteries are sending 24V to the 24V to 12V converter. Is the Solar CC "load output" sending 12V? The battery protect is supposed to keep the DC loads from draining the battery at some predetermined level. Maybe there is a conflict.

What do you do with one cell that drops voltage very very slowly, by single hundredths of volts over time? Incorporate it into the system and keep an eye on it? I've emailed Basen China about the problem and tried to chat with Basen USA via their website; they don't answer. If the other cells...
