Solar+Battery Power Is Now a Reality

Modern Gen-3 Battery  Inverters can now operate with or without batteries.  The solar energy is available even when utility power is out.   Adding batteries enables nighttime power and exact control of when energy is backfed to the utility.  Full solar power is still available when your utility power is out!

Sol-Ark Inverters are preferred for situations where you need full power, but  want the option to be able to disconnect from the utility. You can eliminate some or all of your power use from the utility, or entirely disconnect. This system is the most feature-rich solution of all hybrid battery inverters world-wide.

Now that major utilities have the practice of shutting the grid off preemptively, you could be in the dark for days without notice.  If it is time for a change, here is an powerful solution.

For larger inverters in residential systems where grid feedback is desired, but there is need for supporting heavy load, the PomCube Net-Zero inverter+battery can be cost effective.  You can spin your meter backwards in order to zero your net electric usage. These in inverters maintain daytime power to your home, even when the grid is down.  Battery power enables night time power also. Now you can add battery backup to your solar array.

The rapid expansion of battery technology is opening new possibilities for long-life and reliable battery power in your solar solution

  • Add battery backup to your home system
  • Use battery power when utility rates are high during peak TOU windows
  • Create  “critical load circuits” to ensure refrigerator and well pumping during emergencies.
  • Add off-grid power for remote sites for animal watering

Off grid systems can now support entire house power requirements. Modern battery banks, coupled with powerful power inverters and reliable solar modules provide years of trouble free power.  Backup generators can be used to augment solar production and boost battery charge when needed.

Modern battery banks are assembled from long life lithium batteries, which require no periodic maintenance. The life expectancy is 15 years under normal use. Battery racks come with built in circuit breakers and display panel to show voltage and charge level.   SunnyCal Solar can pre-assemble battery-based systems at our facility, and deliver to your site for same-day setup.

Choices abound for selecting the best battery for your solution.
