Looking to use Signature Solar EG4 battery packs. For floor space reasons, we need a single "foot print" rack that will take 10 to 12 batteries. Does anyone make a rack that supports the weight and current of a battery system like this? Essentially a double 6U Signature Solar rack. Thanks! Sid

I keep seeing half-cell panels being recommended over full-cell panels to deal with shading issues. If you have any shading issues, won't the entire cell be affected? I am assuming that the paired 'halves' are adjacent to each other and are not a top versus bottom split of the panel.

I am looking for a better "power center" to use camping than a bunch of random power banks that are all USB based. I am initially thinking about the Yeti 200x or 500x so, nothing super big or heavy. I am looking to provide some power if my car battery is dead (I travel with a small charger car...

My friend was looking at some YouTube video with a JBD BMS that had an output to drive a couple heater pads for the LiFePo4 batteries. It appeared the heater pads that were attached to sides of the batteries were connected directly to the BMS. Searching Ali Express has turned up some BMS...

I can get another Samlex PST-1500W 48Vdc inverter but, I'm really looking for something bigger and low frequency to tap my ~35Kwhr of usable battery. High frequency is nice but, the durability of low frequency is attractive on its own in addition to its surge capacity and dealing with sustained...

I have read a few things that say I would need to top balance a set of LiFeP04 batteries at 3.65V. What sort of constant current and voltage 'chargers' does everyone use? Anything specific recommended or that should be avoided? As I understand it, I would take my 16 batteries and connect them...

Is there a good guide for selecting the 'right' JBD BMS? I think I need a 120A 48V version but, I'm getting lost in all the different versions. I'm looking at 16 LiFeP04 batteries for 3700W (today) with a possible upgrade in capacity later this year.

Fourth-quarter last year, I was seeing a lot of talk and speculation about 304Ahr LiFeP04 batteries and more recently higher capacities being talked about. Are 340Ahr LiFeP04 batteries just speculation at this point? What is the state of the industry these days and how applicable is it to...

Looking for good LiFeP04 cells for a 48V system, I'm seeing a lot of talk about 304Ahr batteries becoming available with some discussions of higher capacity options. Assuming we limit the discussion to good vendors like Amy and Jenny from China, or similar, are higher capacity batteries getting...

I am looking at a 16x280AH Shenzen Luyuan Technology battery bank but, the whole BMS thing is a mystery at the moment. What BMS systems are good options for this type of setup and what general price range are we talking about? I should note I'm pricing this out against Gill batteries and...

Perhaps I missed this in my search so, if I did please point me in the right direction as I'm a bit surprised I didn't find anything. I have a friend that keeps talking about Saltwater batteries. I have heard a few financial news tidbits saying some large industrial saltwater batteries are in...

I have a friend that mentioned a review of MPPT charge controllers and picked up an outdoor-rated model from Taiwan that doesn't have any brand name on it. It looks interesting and I hit the QR Code on it which took me to a video that doesn't mention the company either. It looks like Esmart3...

Are there good online storefronts or alternative shops (like welding suppliers) to buy wire for my solar panels and related gear? I need two runs (2 wires * 2) with one pair ~25ft long and the other pair ~35ft long plus all the interconnects between controllers, inverters, etc. I will be...

Victron Energy BlueSolar MPPT100/20 I have experience with the Midnite Kidd charge controller for reference. I don't need the $300+ cost and the more advanced feature set so while looking for an MPPT charge controller I came across the Victron 100/20 which looks like a good relatively simple...

L-500W 12V/24V Wind Turbine I am looking to bolster low solar output during Winter. In East Texas, I have had periods of up to two weeks with very low or NO solar output with 10~12 230W panel systems. I have two new systems I'm setting up with more modest power needs. I am looking at a 122Ah...

I am looking for a load that runs 18W~27W. How do I convert this to battery amp hours and what are my better options for batteries that aren't super expensive but, hopefully, aren't maintenance intensive. I'm wondering about the cheap lead-acid batteries I see on Amazon which are sealed but, I...

I'm looking for smaller-sized solar panels for an aerial mounted system. I have an 18W draw so, I'm thinking I will need a little over 100W of solar panel to keep the batteries topped off. I would like to keep 24hr operations but, if they fade out during the overnight Winter periods, I can...

I'm new here but, not new to solar. I have been using a Midnite Solar KIDD charge controller to do things like put heat in electric water elements (keep fish warm overwinter in tanks) and the more classic charge batteries and use an inverter to run things. I'm shopping for pallets of panels so...

I have prior experience with the Midnite Solar KIDD and lead-acid batteries. I'm contemplating a 10Kw array with LiFePo4 batteries so, I'm here to learn about better Battery Management Systems and battery options. Best Regards, Sid

I am trying to work with Amy Wan via the Chinese shopping website but, my search Fu is apparently a bit weak for those two sites. If she or her company has a forum here that I missed, I'd appreciate a link! We are looking at the 280Ahr batteries for basically an off-grid house situation (we...

I have prior experience with a Midnite Solar KIDD and a 24V lead-acid battery setup. I do not want to use lead-acid batteries in my new system and I'm looking into Lifepo4 batteries. The maintenance issues and discharge concerns with Lifepo4 batteries seem to be far superior to my lead-acid...
