I removed a bunch of maybe 15-year old SHARP 165W panels from a neighbors roof, and before tossing them in the dumpster, I decided to test a few of the best looking ones. I leaned 4 of them up in the yard at the proper angle and used a Victron SmartSolar 100/20 charge controller, connected to...

Hi Matt, I have a small cabin in northern SD county, so I'm somewhat familiar with your area - east of Sycuan Casino right?. I think you'll have some hot days in the summer, and cold nights in winter that will require good HVAC. Fortunately, we have a lot of sun year round, so I'd research...

You don't need a $155 charger. How long will it be kept in storage? What is it's current SOC (state of charge)? The battery panel should tell you this. LFP is not like lead-acid batteries that discharge rapidly each month. Do you have any solar panels? Right now (July) in AZ, a 100W panel...

Geez. that is a LOT of used panels. I somehow doubt that he tested them all...

Anyone from Current Connected care to shed some light on why this bare-bones SOK battery is "discontinued"?

I suspect your battery charger (https://www.amazon.com/dp/B09Z25WQPY?psc=1&ref=ppx_yo2ov_dt_b_product_details) is not putting out anywhere near 60A @ 14.2 Vdc, so you're probably not fully charging your 280AH battery in 12-13 hours. It may have worked for the first week or so, or it just took...

Thanks for that pic of your system layout. It helps for troubleshooting. Just for our review: Your original problem is the inverter shuts down in the night due to low voltage, correct? It's possible you have a bad connection somewhere, causing a voltage drop under load, which causes the...

Aluminum Triplex Overhead wire on poles is going to be the lowest cost option, obviously it's what the utilities do from the transformer to rural houses. It would also keep all your equipment together out in the field, which is a good idea. Sure wire on poles are ugly, but have you tried...

When your battery is fully charged, the BMS inside will cut off the charging current (to near zero). You'll need a way to monitor that current, like the current clamp meter recommended above. You should have enough solar power now in S. CA to charge this battery in 6-7 hours using your 800...

To answer your question, No, there are not "relief ridges" on the bus bars between cells. The cells are very firmly mounted and compressed, and probably wouldn't move anyway. You're using 48V Rack Batteries in your RV? I wouldn't recommend this battery in an RV; I'd use a plastic-case...

Your only going to be charging with max 4 Amps, a small ga. 50' extension cord will do. You WILL learn a lot about solar from the Victron app. Or do you enjoy paying the utility company for power?

I recently saw the price of the SOK SK48V100-NCBT drop to $1,099. which I thought was an incredible bargain, considering Will liked it at $1,300. However, on Current Connected's website it now says, "*NOTICE* Discontinued by the Manufacturer" and they are "Out of stock until May ~ June"...

Their website hasn't had any updates about their new Pathfinder BMS since Sept. ??? I would support a product designed in the USA, with good documentation and software support. https://overkillsolar.com/category/pathfinder_bms/

Mine was also delivered yesterday, and has a bent rack bracket also. Since so many people have posted similar damage, I wonder if these may have been damaged that way when unloaded off the boat from China. Mine also had a couple small scratches (<1") on the top and bottom covers, which someone...

As I remember the story, there were fires in some large solar farms, due to oxidation within certain panels. Oxidation causes high resistance which causes heat, which caused fires. The panels were only a couple years old. The panel mfgr was sued, and agreed to replace all the panels. You...
