  • Post in thread: Safe Grid Use of the 5000ES and transformer

    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...
  • Post in thread: Sol-Ark 15k will only invert 13k of DC PV to AC

    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...
  • Post in thread: Wills Video: LiFePO4 Server Rack Showdown! SOK Versus Signature Solar

    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...
  • Post in thread: Safe Grid Use of the 5000ES and transformer

    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...
  • Post in thread: PLEASE HELP - EG4-LL (V1 with updated Victron Firmware) generating Cell Over Voltage at 100% SOC

    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...
  • Post in thread: PLEASE HELP - EG4-LL (V1 with updated Victron Firmware) generating Cell Over Voltage at 100% SOC

    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...
  • Post in thread: Sol-Ark no longer supporting gen shave

    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...
  • Post in thread: PLEASE HELP - EG4-LL (V1 with updated Victron Firmware) generating Cell Over Voltage at 100% SOC

    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...
  • Post in thread: Anderson connectors

    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/...
  • Post in thread: The best and worst BROOMS for wet and dry snow removal?

    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...
  • Post in thread: Sol-Ark 15K with open loop batteries asking for trouble?

    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...
  • Post in thread: Electric water heater off grid

    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...
  • Post in thread: Heating pads under battery

    Maybe use a seedling mat. They have a much lower heat density. There are all kinds of sizes...
  • Post in thread: PLEASE HELP - EG4-LL (V1 with updated Victron Firmware) generating Cell Over Voltage at 100% SOC

    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...
  • Post in thread: Deye Weird Voltage Behavior When Time Of Use is Enabled

    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...
  • Post in thread: Sol-Ark 15K Battery Voltage Regulation Issues

    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...
  • Post in thread: Help needed

    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...
  • Post in thread: Sol-Ark 15k - What parameters trigger Absorb? How to charge to 90% open loop?

    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...
  • Post in thread: How is a EG4 Battery grounded without rack?

    Thanks for the input. That makes sense. I just needed to understand how this was determined.
  • Post in thread: PLEASE HELP - EG4-LL (V1 with updated Victron Firmware) generating Cell Over Voltage at 100% SOC

    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...
  • Post in thread: Solar assistant: do you use it?

    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...
  • Post in thread: Hot water Heat pump, anyone running them in their house?

    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...
  • Post in thread: Sol-Ark 15K Battery Voltage Regulation Issues

    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...
  • Post in thread: Sol-Ark 15K with open loop batteries asking for trouble?

    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...
  • Post in thread: Sol-ark 15k

    I have the same issue. My 15k is stuck at -32 to -33C. Seems like the sensor is not hooked up, or maybe not used? The AC temp sensor is working.
  • Post in thread: Sol-Ark 15K Battery Voltage Regulation Issues

    Are both of you grid tied or off grid? If grid tied, do you sell all excess production?
  • Post in thread: How is a EG4 Battery grounded without rack?

    "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...
