    Closed Loop Comms between Sol-Ark 15k and EG4 LL batteries

    I saw the video uploaded for Victron inverters, I assume that the updated protocol will work with sol-ark as well. However, I didn’t see the new firmware uploaded to the Eg4 electronics website. The firmware here is still the one from 2022-08-24. https://eg4electronics.com/downloads/ Is there...

    Did it ever get uploaded? Assuming you guys are busy with the holidays too. Thanks!

    higher voltage MPPTs are more efficient?

    Thank you for the detailed explanation. I forgot about inline fuses, I was going to go with PV fuse holders but the inline ones will definitely cut down on wiring costs by a significant amount by fusing and parallel-ing the strings near the panels. thus at 450V, the MPPT RS would technically...

    higher voltage MPPTs are more efficient?

    How did you come up with using thirty-six 405W panel configured as 4s9p for the 250/100? ahh yes the RS 450/100 has 2 trackers, so 8s2p per input with 2 inputs would be 32 panels. thanks for catching my mistake. so the potential panel count per controller is relatively the same based on their...

    Please check my paper setup! 48v, dual 10,000 quattro's

    I'm guilty of that, but try my best to read the spec sheets. however, sometimes I'm sloppy :( sorry what's Gx and SG? GX as in Cerbo GX? Thanks

    Please check my paper setup! 48v, dual 10,000 quattro's

    Yes the integration is key, which is why I'm either going to sell the EG4s or wait until they come out with their closed loop setup with Victron

    higher voltage MPPTs are more efficient?

    I'm a total noob, and would appreciate any comments on this. I am figuring out which charge controller to use and came across these two from Victron. Smartsolar MPPT RS 450/100 versus Smartsolar MPPT 250/100 Tr. (both spec sheets are attached below) For example when I use the Victron MPPT...

    (NC) 6x Brand New EG4 Lifepower4 48v 100ah batteries with wheeled server rack

    6x EG4 Lifepower4 48v 100ah batteries with server rack and wheels. Will also come with the cable to communicate with the packs via USB to a PC, and everything else that they come with from signature solar. I paid about 9,500 + shipping, so <10,000 total, received about 2 weeks ago. Asking...

    Please check my paper setup! 48v, dual 10,000 quattro's

    thanks for the responses. 1. I'm looking into the MRBF fuses just because they seem much simpler to mount (straight to the terminal post) and cheaper than t-class fuses. Yes, you're right on the 150a fuse. 2. ya, if everything before and after the shunt is fused, it seems redundant. 3. I'm...

    Victron with eg4 batteries 48v

    FYI, I emailed signature solar about this today regarding if the new LL V2 can act as a master to the "normal" EG4 Lifepower4's and here is the response: sad that I didn't realize this until I got my shipment. looks like I'll have to go another route...anyone need batteries?

    Please check my paper setup! 48v, dual 10,000 quattro's

    Thanks everyone in advance for your comments and help. I've learned a lot by reading the forum. I'm trying to go off grid with generator backup, and have grid access for a secondary backup. I would like to reserve space for future battery banks. So far this is my battery to solar charge...
