I have these units, and have installed these units from SS. Nice unit, works great, no issues. These were received last year, 2021, in Nov.
Yes, the Labeling is incorrect on the Nameplate and the N labeled connections, but SS clearly states that N is L when purchasing. Yes, the labeling does...
I have a dual 15k parallel setup with 40kW DC coupled panels. I can actually pull 32KW from PV to loads/grid, as you can tell it in the app use 18kW of PV.
When I first installed my system I thought I had the same issue as you, as I would flat line clip at ~17kW. There was no setting on the...
I have no problem with SS just selling to their battery owners or buyers. I'd do the same thing, because of supply chain issues. bThey have been out of stock on racks quite a bit.
If I had a potential customer for batteries, but my rack was out of stock due to everyone buying the racks, then...
I posted pictures a couple pages back that show the unit sourced by SS is different than the models that every other distributor sourced, as the screw that others removed to float the neutral, is installed and grounded on the SS unit.
So, SS is supplying and has always supplied the correct...
Just float them while monitoring the BMS tools, or the the battery display. Hold the float so that the bad cell is just above 3.40V(ie 3.45-3.50V). This will allow the cells to top balance(no need to do anything external). The balance current is 100mA so it is going to take weeks to months...
You just have to go with lower absorbs for now. Like I said, just absorb to something around 54.5V and try to keep your high cell from going much above 3.65V during absorb. So monitor that cell while the voltage is rising during absorb, when the cell is around 3.65V, take note of the pack...
It is possible to roll back a Sol-Ark 15k.
I updated my 15K master slave setup a couple weeks ago to the latest FW. I thought it might fix some minor calibration and regulation issues. It ended up causing more problems and not fixing the issues I was having originally. I told them I couldn't...
They told me the configuration #'s mean nothing and aren't used by the battery(it makes no sense). It would be nice to be able to customize the protections.
The battery doesn't shut off until 3.90V high cell. If you hit 3.90V this will trigger OVP, this will in turn trigger the BMS to...
Yes, you can replace them with something else, just make sure they have the proper voltage and current ratings. Best to have the current rating at multiple times your actual usage, as contacts will go bad over time if not cycled.
Anderson connectors do go bad. I routinely deal with melted/...
I use a 2' wide, stiff bristle push broom on a 12' painters extension handle. Works great on all snow from light powder to heavy slush. Haven't scratched any panels. The stiff bristles make it easier to dislodge anything the gets crusted on the panels.
The snow normally adheres to the dirt...
Glad to hear that fixed your problem.
I was excited too, to close loop my EG4LL's, but the problem with the closed loop comms, is that the batteries control the inverter charging with no user adjustment. It will charge to a high bulk/absorb voltage of 55.5-56.0V(my inverter charges 0.5V...
Me too. I have it in out main living area. I pull the hot air off the ceiling from the living space. In winter I just add another log on the fire and in summer it adds some a/c. I vent back to the living space. Also pulls excess humidity out of the air. Only uses about 300W when running...
I'm not sure why you are using Equalize(used on lead acid batteries), but I'm not familiar with Victron. Just use absorb and set so you don't get OV warnings on the battery keep you high cell at or below 3.65V until you reach 100% SOC(if that's what you want).
You should have a setpoint...
I'm going from memory, but what you describe all sounds very familiar. As it depends on how your running the system. It would just be nice for it to do what you tell it to do. The manufacturer should be able to program it to work properly.
For me the 0.5V discrepancy only happens when grid...
It would be easy to just compensate for the 0.5V, if that was just an offset. It would actually be preferable to have this as the problem, as it is a constant.
The problem is, sometimes there is a 0.5V offset, and sometimes there is a 0.0V offset. It depends on multiple factors. So, it is a...
I have a Franklin 5HP 240V 60Hz single phase 3 wire capacitor start submersible well pump that's 300' down the hole(200' to water), that pumps up 50' vertical to the pressure tanks and run 50/70 PSI cutin/cutout.
The thing is a massive load to start and run. But I was able to start and run...
Thanks for the input. It seems like it is probably using SOC(determined by battery capacity) and not the actual battery voltages to go into absorb. I thought it would look at voltages if I was in Voltage control mode. I set the capacity back to actual and will see what happens tomorrow...
I have had the exact same issue with my EG4LL V1 batteries. I had the issue both before and after flashing the firmware for sol-ark. I wanted to close loop my batteries, but the batteries tell the inverter to absorb at too high a voltage.
The issue with the battery is the top balance of the...
SA can be used to just monitor batteries, no need to have an inverter hooked up. I did this when I first hooked up my system and hadn't hooked up the inverter comms yet. Worth it just for the battery monitoing, as it's easy to monitor the cells of each battery and adjust charging parameters...
We have a 40gal Rheem HPWH. Installed in 2021. Just had the issue with bad thermistors causing evaporator temp errors. The unit would ice up or just alarm out and automatically switch to the 4500W heating element. Just put in the new thermistors and it's working fine again. So unless you...
Good to know I'm not the only one. I don't ever see anyone complaining about this issue. I would figure more people would be talking about/noticing this issue to get it fixed. Unless people feel a 0.4-0.5V deviation from set point is ok. I brought it up a couple separate times with Sol-Ark...
The EG4LL v2 manual say Bulk at 55.5V +/-2% and Float at 54.0V +/-2%. These use the same cells as all the EG4 batteries.
Sol-Ark techs gave me 54.4V bulk and 54.2V float. So, they have a range of #'s they are giving out.
I have a couple problem batteries where if I Bulk absorb higher than...
"1. Grounding wire. Affix a grounding wire of sufficient wire gauge from the battery module enclosure grounding screw (located on the front panel) to the rack frame (or cabinet) earth ground point."
I have 12 of these 48V 100Ah batteries that are not in a rack and are sitting on a wood frame...
