    With Sol-Ark's remote access features and app you are never out of touch to quickly repair or adjust any system without being on site.

  • Split Phase & Three Phase
    Sol-Ark’s 15K pumps out power just like the grid, allowing you to power 120V/240V/208V appliances

  • Grid-Tied, Hybrid, Off-Grid
    Reliably manages power from Solar, Battery, Grid, Load, and Generator simultaneously

  • Warranty and Reliability
    No need for additional warranties. Comes standard with our award winning iron clad 10-year warranty right out of the box and our 7 day a week live support to assist you in all your needs.


  • Is it possible to program or setup the Sol-Ark 15K remotely?
    Yes, this feature comes standard with the Sol-Ark 15K.
  • Is the Sol-Ark 15K stackable?
    Yes, the Sol-Ark 15K can be stacked with up to twelve Sol-Ark 15K's in parallel in a 120/240VAC or 120/208VAC system. All temperature and CT sensors would connect to the Master and the Master unit will control charging. When programming, you would place both the Master and Slave(s) in parallel mode. The Master is always assigned Modbus Serial Number 01, whereas the Slaves would be assigned "02", "03", "04", ...etc. All units in parallel must share one battery bank.
  • What components are recommended for Rapid Shutdown?
    Tigo TS4-A-F, APSmart, or MidNite Solar.
  • How do I AC couple my Sol-Ark 15K inverter?
    Refer to the Sol-Ark 15K Load Side AC Coupled Wire Diagram 120V/240V on pages 9 and 10 of your installation manual. When AC coupling, you can either connect to the GEN or the LOAD breaker. An advantage of connecting to the GEN breaker is that your Sol-Ark inverter can accurately monitor the AC coupled system. Using the Sol-Ark monitoring service, you will be able to monitor the AC coupled inverter production as well as the Sol-Ark’s production.

    A disadvantage of connecting to the LOAD breaker is that although you will be able to monitor the AC coupled system, the data may not be accurate. This is because your critical loads panel (or “back-up panel”) will use power from the AC coupled inverter before power goes through the Sol-Ark.

    An advantage of connecting to the LOAD breaker, is that the LOAD breaker is 200 amps versus the GEN breaker’s 100 amps. If you are at risk of overloading your 100A GEN breaker, you may need to consider connecting to the LOAD breaker instead.

    Keep in mind, that if you have loads on the LOAD breaker, you can use the GEN breaker for AC coupling, a generator, or for a smart load, however, if you are AC coupling to the LOAD breaker, then you won't be able to use the GEN breaker for anything else.

    Once your connections are made, refer to page 33 of the manual for AC Coupling Settings.
  • Does the Sol-Ark 15K have a built-in transfer switch?
    Yes, the Sol-Ark 15K has a built-in transfer switch that will switch from grid to battery bank automatically.
  • Does the Sol-Ark 15K include a Remote Temperature Sensor (RTS)?
    Yes, the Sol-Ark 15K includes a hardwired RTS that connects with two wire leads.
  • Will the remote temperature sensor work with lithium batteries?
    Yes, it will work with lithium batteries, but it will not be necessary if the lithium battery has an onboard Battery Management System (BMS).
  • I would like to use the MidNite Solar MNBCB Battery Combiner Box with my Sol-Ark inverter and battery bank. Should I use the one with the 50mV or 100mV shunt?
    You can use either battery combiner box because unlike other inverters, the Sol-Ark inverters already have an intergrated shunt, so you may not be using the shunt that comes with the battery combiner box.
  • Why doesn't my Sol-Ark inverter have a serial number on it?
    There is a QR code on the unit which is programmed with the serial number.
  • Can I use my back-up generator with the Sol-Ark?
    Yes, as long as the generator voltage matches the Sol-Ark's voltage settings (e.g. 120/240 and 120/240 or 208 and 208).
  • I am connecting my batteries to the Sol-Ark and need to know what Amp-Hour Capacity to set. How do I determine that?
    Take the per battery Amp-Hour Capacity (aka "Nominal Capacity") and multiply it by the number of batteries in your battery bank. That is your battery bank's Amp-Hour Capacity (aka "Nominal Capacity").
