Frequently Asked Questions

Q1: Is this big enough to run my whole house?

It depends on your energy usage. The 12K provides 9kW of continuous power, which is enough for all essential loads (lights, fridge, internet, well pump) and some larger appliances like a microwave or small A/C. For larger whole-home needs (like central A/C and electric heat), you may need the Sol-Ark 15K or 18K.

Q2: Can I use this without batteries?

Yes. It can function as a grid-tied inverter without batteries, reducing your electric bill. However, you will not have backup power during an outage unless batteries are added.

Q3: Does it work with my existing solar panels?

Yes. The Sol-Ark 12K supports AC Coupling, allowing you to connect your existing grid-tie inverter (like SolarEdge or Enphase) to it, using that energy to charge batteries during an outage.

Q4: Can I add more power later?

Yes. The 12K is stackable. You can parallel up to 8 units to increase your total power output and battery charging capacity as your needs grow.

Q5: Do I need a separate charge controller?

No. The Sol-Ark 12K has two built-in MPPT solar charge controllers, saving you money and simplifying installation.
