I'm posting here to share some insights I recently gained while helping a client. I had to reach out to AIMS Technical Support, who confirmed that their manual is lacking in detail and could be improved significantly. Unit installed Link to manual I have a client who had another solar...

This is not a quiz or a trick question, just looking for anyone's honest feedback regarding what they think is incorrect about this setup of EG4 batteries.

If I have 3x 12v batteries connected in the following configuration. 1: 100 amp 2: 100 amp 3: 70 amp So, if batteries 2 & 3 (Group A) are put in parallel, it's 12v at 170 amps. If I put battery group (A) in a series with the 1st battery, I have 24v now. So my math memory recalls that you...

I'm not familiar with the Growatt product line besides having seen and knowing of them. I've seen Growatt inverters that are single-phased paralleled to get split phase, but what I'm wondering is if you can stack these larger inverters, similar to EG4 and Sol-Ark inverters. I looked in the...

In December of 2022, I ran the Sol-Ark panel calculator using the following panels and the calculator said I could run 30 of these panels. Panels are Risen 550W. (See attachment for specs) The output of the calculator: Recently I re-ran the calculator to see if anything might have changed...

Just wanna ping the forum to see what you think and any guidance. In this scenario, I have an EG4 6000 EX which has the following PV limits. Watts: 7500 Volts: 500 Amps: 27 Mppt: qty 1 Panels: Sunpower 305 Watt Solar Panel Model: SPR-305EL-WHT-D Voc 64.2 imp 5.58 My basic calculation (not...

As the title of the thread says I’m looking for community validation/clarification. Background: I’ve got a potential project to inspect multiple off-grid homes and their solar systems. For purposes of scope I’m simply interested in evaluating if these home owners have over spent on large...

I'm looking to get a quick thread going for all the Sol-Ark 15K owners to provide any information they have so I can compare. I've been working on a low current issue affecting my SOC and immediately after installing a Victron Shunt in front of the Sol-Ark, I'm noticing what seems to be a...

Everything is working fine, but I noticed this little faint warning symbol under the battery on the display. There are no warnings in the logs, I've rebooted everything and it still persists. The manual doesn't explain it and I can't find anything in the forums. Does anyone know what this...

I wanted to share with the community how I was able to get Solar Assistant "SA" to read all my inverter data from my Sol-Ark 15K, AND also read all the individual battery data from my EG4 LifePower4 batteries so I get the best of both worlds, thorough data from "each" of my 12 batteries and all...

I've searched the forums but I'm not able to find a description of what the Sol-Ark receives from the communication hub. In my Sol-Ark from what I can tell it simply sees one large battery which increases in amp hours by increments of 100 as I add additional LifePower4 batteries. Is the...

I have an EG4 communication hub that did not come with an inline fuse, can anyone share what fuses they have used for this? My system is 48v. Thank you!

Hello and thank you in advance. I’m trying to do a PV string size calculation and I’m wondering if anyone has a link to a calculator that would allow me to determine the correct configuration of panels that safely be hooked up to a single Schneider Conext MPPT 80...

I have 2x racks of 6x EG4 LifePower4 batteries, I'm using the Communications Hub and I'm wondering if there is a preference for connecting the batteries to the Hub. For example: the manual for the Hub says that each RS485 port 1&2 can handle 15 batteries. Since the batteries, 6 each are in...

Just want to confirm that each polarity of conductors must be the same length, not the entirety of all conductors. For example in the picture below, the red wires are 5 feet from the bus bar, while the black is 8ft from the bus bar. Is this correct, if not why?

Hi everyone, I've been thinking recently about the topic of optimal battery life settings in an off-grid situation. Like everyone else here, I would like for my batteries to last as many years as possible without compromising "too much" on their convenience. In other words, it's probably more...

Could I charge each 12V battery in the 24V bank without disconnecting the lead between the two batteries? The reason I ask is that when I want to use my 12v Victron smart charger to charge them up, it would be easier to not have to remove the lead between and then come back and move the charger...

Hello, I'm wondering if anyone would be willing to show where they have their PV breakers installed. I'm putting my install in an underground garage and was considering surface mounting the breakers on cement board and was just wondering if the community would share photos of how they did...

Edit: 4/14/24 I’ve done the research since this initial post and this stuff is terrible. The Sol-Ark is great but the batteries they were selling without BMSs and still have no closed loop communication where over price and literally incomparable to quality of any EG4 battery. The guy that...

Trying to understand where does this other 4500W go if the maximum is 15K?

This is hopefully a quick easy question. I’m reading the manual for the 15 Sol-Ark trying to make sure the AC units I wanna use will not trip the inverter. https://www.sol-ark.com/wp-content/uploads/15K-2P_SpecSheet.pdf So if I’m reading this right, the Sol-Ark 15 can surge it’s output to...

I'm new to this stuff and I'm not easily finding an answer I've been trying to understand with regards to a new install. From page 15 of the manual, I understand that each PV input can accept up to 500V not to exceed 18A. For PV1, if I took 8x455w panels with a Voc of 49.35 and I create two...
