Has anyone used the 18K in conjunction with the zero export feature? I have the solark 15k and it has a similar feature called limit power to home. Does the 18k by EG4 come with current sensors and does it back feed your main panel as it senses current flowing from your meter to loads in your home?

I'm thinking about adding another battery to my battery bank. I had a generally good experience with Docan tech, so I started shopping around on their Alibaba page. Things seems to have gotten cheaper per kwh for certain models and lots of LiFePO4 cells (I have lots of theories) and I was...

I rebuilt an older Midnight Solar combiner box and I was pleased with how it turned out. As my peak current is under 30 amps I like using recycled bus bars or ground bar kits from the store with polyester standoffs from Amazon rather than paying extra for oversized bus bars branded for solar...

I saw Will's latest tear down video on cheap 12 volt batteries, and I was wondering, has anyone bought and used the 48 volt 100 AH Vatrer server rack battery? (this is Will's affiliate link to their Amazon page)...

Location Forsyth county North Carolina. New in the box! These are warranty replacements direct from Signature Solar. I bought a Sol-Ark to replace my 6500 pair which failed and no longer need my replacement EG4 units. They are currently sitting in my living room unopened and I'd love to sell...

Saw this in an email from Renvu. Looks like a great way to turn the ground under your solar field into a lifeless desert. But it could be a good option for some people. 40 year lifespan, High Density Polyethylene https://www.renvu.com/PowerField-Energy-PowerRack-Solar-PV-Ground-Mount-System

I decided to go a different direction after mounting this 6000 split phase unit in my solar power plant. Unused, powered up on the battery bank to confirm it functions. 160 amp Suntree DC breaker and 2 AWG leads also available for sale. Precharge resistor included for free. DM me with your...

This are crazy cheap at Lowes Home Improvement, $29, 16 feet, black and red gives you 32 linear feet. Now, they might not be pure copper inside, but I used them when I ran out of THHN from Wire and Cable your way on wiring my last 16s cell pack to the battery bus bar. They crimp great in a 2...

Hi friends, setting aside the cost of batteries, having checked the prices of friends gird tied system vs my DIY system, I feel like hiring solar installers is at least double the price for the same amount of solar generation and hardware. Has anyone gone through the process of being grid tied...

Hi, I'm looking to upgrade my system and looking at either two EG4 18kpv or two Victron Quattro 48/10000 with the Smart Solar MPPT RS 450/200. Going with Victron system seems like the more robust option in terms of powering loads and surged capacity, although it will cost slightly more and has...

Hi friends, has anyone currently operating the EG4 18K observed excessive amounts of heat running it at its advertised capacity, either maxing out the PV generation or maxing out AC output? The specs on the EG 18k are impressive, but I'm worried it will die on me in a year if its build quality...

Hi friends, has anyone found any good literature on dendrite formation in Lithium Iron Phosphate batteries? Is there much difference in the formation of dendrites be Lithium Cobalt Oxide (18650 lithium ion cells for example) and LiFePO4? I'm assuming LiFePO4 is less bad, hence why it's being...

Hi, this past weekend my system of two EG4 6500EX-48, paired for split phase operation, shut down around 1 PM. One of the units had fault 02, which is over temperature aka it was too hot! Both inverters are in a basement with an ambient temperature of 60 degrees F. At solar noon each each...

Hi, I am upgrading my battery bank and need longer bus bars. I'm using a 12x12 inch Wiegman box with 2 inch wide, 1/4 inch thick copper bus bars. I plan to attach 5 inverters/charge controllers (48 solar panels) and 6 batteries (75 kWh) using 2 AWG wire on 1/4" screw terminals. In addition to...

I noticed in tear down videos of the EG4 and Jakipier batteries that the EG4 has a pre-charge resistor permanently installed. Does anyone know how these are wired in a permanent installation? I'm planning building to build a battery bank of multiple 48v16s groups of LiFePO4 cells wired to a...

Hi, this spring I purchased from Signature solar the EG4 24v packs that go inside their server rack batteries. I was attracted to them based on the price, preassembled framing, and soldiered bus bars. However, given space limitations in my battery rack build, I would like to sell them and use...

Signature Solar sold the 8 cell packs, 24 volts 100 AH, inside the EG4 batteries earlier this spring. Will Prowse reviewed them and said he thought they were a great deal. I bought 6 to make three 48 volt 5.12 kWh. Due to space constraints I'm considering selling them and buying one set of...

I got an email from Daisy from Docan Power that they are coming out with a 48v LiFePo4 server rack battery that looks a lot like the others already on the market. I cannot wait for Will to do a tear down video if they send him one. I've never had any issues with the cells I've purchased from...

Hey y'all, I would love some clarification. Why does Will say on YouTube that the neutral-ground bond on various all-in-one units such as the MPP LV6548 and the new EG4 unit he just reviewed are bad when using two units to run split phase? Is the issue that you would have neutral bonded to...
