Hi all. I have an Enphase Ensemble system. 3 Encharge 10s on the wall, Empower and Envoy. All the backup loads are on a 200A panel. But...I have 2 200A panels tied to my meter. The OTHER 200A breaker contains the loads that are NOT backed up. Can I use an all-in-one inverter, with a server...

2 brand new Victron Smart MPPT Controllers for sale. $595 (each) plus shipping UPS Ground Never used. Originally part of a project never completed as we sold our fifth wheel.

Struggling with the cost of the Enphase system when compared to what I would get from using 2 Sol Ark 12k inverters with 30kw of batteries from HomeGrid (or other). Any advice? I just don't want to overpay. My roofline is almost always in the sun, so do I really need microinverters? Thx.

I am new to the group but not new to Wills videos. I am struggling to make a decision about what type of battery backup system to use. Cost is a large factor. EG4 server units are clearly the cheapest. But I'm not sure how they compare against, e.g., Fortress eFlex. The Fortress batteries are...

Brand new, never used. Will ship in original packed box. $2000 OBO Local delivery in Charlotte, NC Otherwise, shipping cost can be added and would be based on weight and location.

UPDATE: Cerbo Gx and Smart Shunt sold. Remaining components Hi all. I started a project but never finished. All equipment is brand new and available as a set or by component. If local to NC, pickup is recommended due to weight. 1. Quattro 24/5000/120 - $2700 2. 2 Smart MPPT Solar Charge...

If anyone has one for sale, please message me. Thx.

Hey all. In my 6/4 flex romex run from my RV's 50A plug to my Victron Quattro, I need extra length for one of the 2 120v hot legs. I assume it is fine to connect 2 runs of 6AWG with a positive bus bar. But I also assume the connection should be fused. 100A ANL fuse ok?

Hi, If anyone has 8 gently used 280ah EVE cells, I may be interested. I could pick up so no shipping needed. Thx.

Folks. Don't leave your charger unattended. Left mine on overnight and woke to find my 1s8p cells I was trying to top balance at 4.7v. They are way swollen and I'm considering them DOA. Lesson learned.

I am charging 8 280ah LiFePo4 cells in parallel using a TekPower TP1560E power supply and an iCharger x8. I have all parameters set and the iCharger Life profile at 3.6v and 30A. All cells are hovering around 3.3 and have been for what seems like forever. Even though the iCharger is set to...

Hi all. I'm working on my new system and am wondering about some things that are likely old hat to the veterans in the group. I have a Quattro 24/5000/120, coupled with a 24v 8s2p 560ah battery bank and a Victron Smart Shunt. I have 2400w of solar on the roof in 2 arrays (both arrays of 6 are...

Hi all. I'm trying to decide between a single Victron 24/5000/120 Quattro and 2 MultiPlus 24/3000 units in parallel. I have a 50A RV in the typical setup where 1 hot powers half the circuits and the second hot powers the other half. I understand I can use a MTS and a jumper to ensure my entire...

$2600. New in the box. Never used. I've just decided to go with 2 Multiplus inverters in parallel instead. These sell for $2,900 + tax (~$200) + $250 for shipping. Will sell for $2,600 OBO and would be willing to meet in NC, SC or VA to save shipping. Otherwise, will ship at cost. Thx. John

Hi all. I am seeking a resource to determine the proper settings for my Victron smart 250/60 SCC. I have 2 8s 280ah battery banks connected in parallel, so 24v 560ah total. I purchased them from a third party so I don't know how to yell who made them. Thinking CATL but not sure. Attached are...

Hi everyone. Any pointers when installing a 3 way manual transfer switch as part of my solar setup for our 50A RV what guage wire I should be using on the switch. 10AWG works well but 6AWG does not. Thoughts? Thx!!

I have 8 brand new 280ah cells for sale for $1000. I top balanced them and had planned on using but now have a family member in need. I'll sell 4 for $500 as well. I'd sell this complete battery pack of 8, with Overkill Solar 8s BMS, for $1250. I'm in NC so if anyone is interested, DM me. Thx.

Thanks for your advice.

I have two 8s banks. Trying to decide whether to place them together in 2p and build one large compression box or build 2 smaller boxes and run 2/0 to parallel them together. Adv/Disadv to either of these choices? Thx.

I need 1 280ah VariCore cell. One I received is bloated. Anyone have one to sell?

Can anyone point me to a resource for establishing an automatic transfer from grid power to solar charged batteries during a power outage? I assume there is a way to do this. The well pump is my sole application for the solar array. Thx.

I have my Overkill 8s BMS connected and a capacity test running. FINALLY managed to get the data screen up after several attempts. However, when I switch to Parameter Settings, it just sits there at 0% and 0/52 forever. Am I doing something wrong? I've cleared cache, uninstalled amd...

Hi all. I am doing my first top balance of a 4s 280ah pack. Now in parallel stage. When checking individual cell voltage, should I disconnect the charger? If not, I assume I am not getting accurate readings and am only testing voltage drop? Thx.

I originally bought these from San Tan Solar, but they will not fit my application. According to STS, they are all in good working order. Palletized and ready to ship. Shipping cost will depend on location.

If anyone has 12 for sale, please let me know. Thx.

Hi all. First adventure into battery building. I attempted to pre-charge my 8s 280ah pack, wired in series and connected to an Overkill Solar 8s BMS set to stop current when a cell hit 3.65. All cells but 3 were matched at the factory st 3.3. The other 3 were 3.4, 3.26 and 3.28. After...

Hello all, I'm planning on building 2 8s 280ah battery packs, each with its own 8s Overkill Solar BMS, and connecting them in parallel so I can have a 24v 560ah system. Does anyone have a diagram showing such a pack? I'm assuming the total 8s2p has a main negative and a main positive that...

Hi all. Still new to the community. I am installing a total of 8 385w Jinko panels. Originally, I had planned 2 strings, each in a series-parallel connection. I had planned on using 2 250/60 controllers. Then, someone told me I could go with a 150/85 for each string if I wired each string in...

Just posted something similar in the solar panel forum. Anyone on here from the SE or Mid-Atlantic U.S. and find it exceedingly difficult to source prismatic cells locally? I'm interested in starting a co-op to combine buying power and buy large volumes for distribution locally or regionally...

Hello all. I'm curious if anyone thinks there is a business case to be made for a solar panel and battery distribution co-op in central NC or the SE in general. Seems like most interest and vendors are not in the SE and that it is difficult for folks (shipping costs, e.g.) to get access to...

Hello. I'm looking for 4 280ah cells with bus bars and lugs. Anyone have just 4 for sale? In NC so hoping to buy from here in the US from someone that has extras.

Hi all. From 24 280ah cells, I intend to build 3 batteries of 8 cells each and each with its own Overkill Solar 8s BMS. Query: should I arrange the 8 in series and then connect the 3 batteries in parallel? Or something different? Ultimate goal is to have 24v 840ah bank. Thx.

Curious. Can I keep my 12v LA batteries that run my lights, etc. on one side of a transfer switch, with shore power as 2 and my LifePo4s as 3, connecting through an inverter directly as a separate input into the breaker box? Isnt this possible in theory, such that I could simply disconnect the...

Hi all. Newb here. I have reviewed some of the other posts on this subject but I dont see a 1:1 for what I want. I am looking to have a total bank of roughly 1600ah at 24v. I'm also looking for the cleanest and most user friendly BMS to attach to the 3 parallel connected 8 cell banks. Do I...

Hi all. New to the group. Will indicates for inverters larger than 2000 you should go with a 24v setup. Originally, I was thinking of a 12v setup connecting 3 12v 300a battery banks in series. But, I intend to use a MultiPlus 3000. So...instead of running 900a total, do I get the same (or a bit...
