Sol-Ark's 8kW hybrid inverter solar system incorporates a battery-based inverter, charge controller, display with remote monitoring, auto generator start, load center with breakers, rapid shutdown, and WiFi connectivity into a single pre-wired system enclosed in an outdoor-rated housing.

In addition to the easy installation of the single pre-wired housing, Sol-Ark 8k has also excelled in the area of PV-to-AC efficiency, boasting a CEC-weighted efficiency of 96% (peak performance up to 97%) - meaning a smaller solar array can be used to get the same amount of power as systems with other inverters.

This hybrid inverter solar system simultaneously manages power to and from a solar PV array, a battery bank, the grid, a backup generator, and your loads. It supports 8kW of continuous power for off-grid production, and up to 8kW continuous for grid-tied production.

Being pre-wired with so many system components already integrated, Sol-Ark's hybrid inverters make a great choice - and an easy installation - for larger single-family sized off-grid, grid-tie, or battery backup solar installations. For very large systems, use the Sol-Ark 12Ks, which can be combined for up to 8 units stacked in parallel.


Applications for a Sol-Ark 8K Hybrid Inverter System

The Sol-Ark system is great for off-grid PV systems, AC coupling an existing grid-tie system, or as the heart of a brand new grid-tie system with battery backup, offering the following operation modes:

  • Sell power back to the utility to reduce your electric bill with Grid-Tie Mode (for net metering where service current is 200A or more, you will also need a pair of 200A current transformers)
  • Zero your electric bill without adding a new smart meter with Meter Zero Mode
  • Use solar and batteries to minimize consumption of grid power when it's most expensive with Time-Of-Use Mode
  • Use Smart Load Mode for a programmable output for high-power off-grid loads or grid-tied time-of-use loads to run only when there is adequate solar power available


Sol-Ark 8K Hybrid Inverter System Features

  • Listed to UL1741-SA, California Rule 21, and Hawaii 14H grid requirements
  • NEC-compliant with rapid shutdown
  • 5-year warranty


Sol-Ark 8K Hybrid Inverter System Design Considerations

  • Primarily designed for grid-tie and standalone off-grid applications
  • Maximum PV input wattage is 11,000 Watts (5500 Watts per MPPT)
  • Damage will occur if the PV temperature compensated Voc (for the coldest temperature expected) exceeds 550V
  • PV production stops if voltage exceeds 500V (500 Voc max)
  • Each parallel string of solar panels on a given MPPT must be the same voltage - however, each MPPT can have a different voltage (number of panels in series)
  • Max number of solar panels in series:
    • 10 (60-cell panels)
    • 9 (72-cell panels)
    • 6 (96-cell panels)
    • Note that these are for reference ONLY; always calculate maximum voltage for your specific solar panels and string sizes
