Selling my charger controller that I purchased brand new and used for about 6 months. I upgraded to a higher voltage unit and I won't be needing this one. It's in perfect condition, not a scratch. Asking $300 and I'll ship within lower 48 states. I'm in Charlotte area and I could deliver...

I'm selling my EVO 4024 inverter/charger. Shortly after I bought it I decided to go to 48V system and I purchased 48V split phase unit. This 4024 inverter was in service for about 2-3 months total under very light load. You're basically buying a new unit. I kept it as a back up since I thought...

This controller is for sale, never used, just updated firmware. I changed my mind and I need to go to higher voltage unit. Price is $700. You're saving about $150 , they sell for just under $800 + tax. I can split shipping cost in lower 48 states. I could probably also do an exchange for 250/70...

I'm not sure this was ever discussed here, most likely yes. But I'll ask anyway, I can't seem to find much about this. I have two Victron Smart controllers MPPT 150-35, identical units and I'd like to connect my array that brings about 50-60 amps into it as 1 array. I don't want to split it and...

Hi . I recently received 8cell 24V BMS from Overkill solar and the first thing I noticed was the long wires from BMS to each cell. They measure 3ft long. I wonder if it isn't a little overkill (no pun intended) . This is my second BMS with the same specs from them and the first one had those...

Hello I'm currently using 8 12V panels, where 4 of them are connected to create 48V array, so total 2x48V in parallel. I think I might have enough space to add 2 more panels, so here is my question. Can I just add 1 of the each new panels to my 48V array, so I'll have 2 arrays at 60V ? My...

Hello, I'll be expanding my battery bank to double the capacity. I wonder what is the best way to wire it. Currently I have 8 cells at 280Ah (EVE cells) with one BMS of course. If I add 8 more cells to keep it 24V, can I just make it one bank and use one BMS? I'm thinking about going 2 cells in...

Hello All, I currently have 24V battery bank , it is 8 EVE 280Ah cells, I have about 30 cycles into it, not much. I decided to double it and make it a 24V 560Ah bank. But I'm looking at Lishen 280Ah cells, mainly because of price. I'm hoping they are close enough in parameters so it won't matter...

Hi, I put together my 8S, 280Ah 24V battery (LiFePo4). All cells when they arrived were a perfect match and are still now at 3.284V each cell. I wonder if I should just connect BMS and be done with it or I should bottom balance them before use. Any opinions on that? Thank you.

Hello, Does anyone know of any quality inverter with low or non existing interference with my HAM radio equipment ? So far most of them I tested (mostly chinese made) produce a lot of noise. Looks like Samlex is one of the better ones, is there anything else on market worth looking at? The specs...

Good Morning, I currently have 12V system which I'm going to upgrade to 24V with more capacity. My Sun Extender AGM batteries are getting to the end of life after almost 10 years and I will go to LiFePO4 now. I'm strongly thinking those new CALB cells , I would get 16 of them and make a 24V...
