1. Overview
Thank you for selecting the MPPT solar charge controller.

The MPPT is essentially a smart DC to DC converter which has been optimized to harvest maximum energy from the PV array in battery based solar electric systems by using a variety of maximum power point tracking (MPPT) strategies.

The controller’s secondary objective is to ensure that the batteries receive a full charge without becoming overcharged.

This is accomplished through a four stage charging process.

Please take the time to read this operator’s manual and be familiar with the controller.

This will help you make full use of the many advantages the MPPT can provide for your PV system.

The mounting location is important to the performance and operating life of the controller. The environment must be dry and protected from water ingress. If required, the controller may be installed in a ventilated enclosure with sufficient air flow. Never install the MPPT unit in a sealed enclosure. The controller may be mounted in an enclosure with sealed batteries, but never with vented/ flooded batteries. Battery fumes from vented batteries will corrode and destroy the MPPT circuits. Multiple MPPT can be installed in parallel on the same battery bank to achieve higher charging current. Additional parallel controllers can also be added in the future. Each MPPT must have its own solar array.
CAUTION: Equipment Damage or Risk of Explosion
Never install the MPPT in an enclosure with vented/Flooded batteries. Battery fumes are fl ammable and will corrode and destroy the MPPT circuits.
CAUTION: Equipment Damage
When installing the MPPT in an enclosure, ensure suffi cient ventilation. Installation in a sealed enclosure will lead to over-heating and a decreased product lifetime.
NOTE : Mounting
When mounting the MPPT ,ensure free air through the controller heat sink fins. There should be at least 150mm of clearance above and below the controller to allow for cooling. If mounted in an enclosure, ventilation is highly recommended.
