Charge Controllers

We design each solar power system to meet your needs. These are the controllers we most often recommend and install for our customers, but by no means are they the only options available.

The Marine KID is the most versatile medium sized charge controller on the market. Ideal for small renewable energy systems (boats, RV’s, Cabins). The KID allows for true input paralleling. As your power needs grow, add more modules to the array and a second KID. This will give twice the power from a single array. Available in Black or White.
The KID comes standard with the mounting bracket, 4ft of Flexible conduit and Battery temp sensor.

The Classic line of MPPT charge controllers are one of the most powerful in the RE industry. The Classics substantially outperform the flexibility, features and range currently found on MPPT controllers at an incredible price.

All Classics are Solar, Wind and Hydro capable.  Each mode is fully adjustable to allow the user to fine tune to their input source.

My MidNite is a free web based monitoring solution that MidNite Solar offers to its customers. It allows you to monitor your charge controller from anywhere you have Internet access.

With all Classics you receive reliability, functionality and an incredibly powerful MPPT charge controller.

Midnite Classic Charge Controller Specifications

The innovative FLEXmax MPPT software algorithm is both continuous and active, increasing your photovoltaic array power yield up to 30% compared to non-MPPT controllers. Thanks to active cooling and intelligent thermal management cooling, both FLEXmax charge controllers can operate at their full maximum current rating in ambient temperatures as high as 104°F (40°C).

Included in all of the FLEXmax Charge Controllers are the revolutionary features first developed by OutBack Power, including support for a wide range of nominal battery voltages and the ability to step-down a higher voltage solar array to recharge a lower voltage battery bank. A built-in, backlit 80 character display shows the current status and logged system performance data for the last 128 days at the touch of a button. The integrated OutBack network communications allows FLEXmax series Charge Controllers to be remotely programmed and monitored via a MATE system display and provides unrivaled complete system integration.
