Microgrid Energy System

Solar Plus has a brand new hybrid solar system utilizing PV, batteries, generators, and automation. It has its own approval process by KIUC to take you off-grid, but use the grid as backup. Our new off-grid systems allow you to put in as large a solar PV system as you need for your energy consumption or budget allows. 

We use automation to prioritize the use of your new system and how your energy flows through the microgrid. Our system allows you to add more PV or storage as your needs change, always with the grid as the back of the line. Solar Plus is the first company on Kauai to use this technology. 

How Microgrids Work

A microgrid refers to distributed energy resources and loads that can be operated in a controlled, coordinated way; they can be connected to the main power grid, operate in “islanded” mode or be completely off-grid.

You can convert any current PV system to off-grid! It works by taking energy from your solar panels and storing the energy in batteries. Due to our utility’s current energy buyback program and the reduced rate they offer for excess power, storing your power for later use provides a greater financial benefit.

Benefits of a Microgrid

It’s Your Energy

Go off-grid, use the grid for back-up, and take control of what makes your energy and how you use it!

New Battery Tech

New long-life lithium iron phosphate battery technology and automation have changed the game!

Sol-Ark Microgrid Inverters

Six years ago, founder Doug Phillips, stumbled across an upstart Hybrid-Inverter manufacturer at the Solar Power International trade show. The company claimed that its clean-sheet design was not only more efficient than its competitors but had the ability to operate in true “zero-export” or “self-supply”. These features were an industry first for residential-scale inverters, and have since allowed us to perfect our residential microgrid model. 

On top of this, the company maintained that its control suite offered more options for customization and that its team of engineers would continue to develop and improve the product with over-the-air updates. This upstart turned powerhouse is known as Sol-Ark, and they have exceeded even our loftiest expectations. Our partnership has evolved as Solar Plus does beta testing and repair for Sol-Ark in the State of Hawaii.

A Partnership

The Sol-Ark inverter has proven itself to be in a class of its own for its versatility, efficiency, and reliability.  They have routinely turned Solar Plus feedback into new features and functionality that both optimize their product for Kauai’s unique energy portfolio and help future-proof their design as grid-tied solar becomes more regulated around the world. Today we believe their product has no true rival in the space; it provides both exceptional performance and value, while arguably offering the consumer the most control of their energy.  

Sol-Ark has recently ventured into the light commercial sector with its new 15kW, 30kW, and 60kW inverters that have the ability to scale up to hundreds of kW. For our customers with commercial property, Solar Plus has scaled up the self-supply with grid backup.
