A MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.

The PWM controller is in essence a switch that connects a solar array to a battery. The result is that the voltage of the array will be pulled down to near that of the battery.

The MPPT controller is more sophisticated (and more expensive): it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement, of the battery plus load. Thus, it essentially decouples the array and battery voltages so that there can be, for example, a 12 volt battery on one side of the MPPT charge controller and a large number of cells wired in series to produce 36 volts on the other.

Maximum Power Point Tracking features an indirect connection between the PV array and the battery bank. The indirect connection includes a DC/DC voltage converter that can take excess PV voltage and convert it into extra current at a lower voltage without losing power.

MPPT controllers do this via an adaptive algorithm that follows the maximum power point of the PV array and then adjusts the incoming voltage to maintain the most efficient amount of power for the system.

Harvest Solar Energy offers an entire line of solar powered refrigerators, solar powered fridge-freezer, solar powered freezers and our newest addition the solar powered medical refrigerator.

All our units are dc powered and can operate independent of the electric grid. Requiring as little as 75W-150W of power, the entire line of dc powered solar refrigerators can operate using a Two solar panel and a single battery. All units can work with either a 12V or 24V battery and can provide multiple days of operation on a single charge. If electricity is available, an optional ac adapter may be added to provide additional security and backup power in case the batteries are fully discharged.

Specifically developed for use with the harvest Solar HSP-P/M Series Panels.

These mounts are universal in design and can easily be adapted to work with most other solar panel brands.

All harvest Kits are made using rust free Aluminum and come complete with all required stainless steel hardware.

The components of the MC connector system for photovoltaics are designed to allow time saving and safe serial and parallel wiring of PV modules for building-integrated and free standing solar installations.
For practical use the connector systems MC3 and MC4 are available, depending on the existing modules or inverters.

Solar water pumps are often used in remote areas where the cost of running traditional water piping is cost prohibitive or you just want to provide water to an off-grid home. Solar water pumping systems are also used to pump water for livestock and crop irrigation.

Solar water pumps are different from regular AC powered pumps in more ways than the simple fact that they use DC power instead of AC. Most solar pumps are designed to be used in off-grid situations, and are designed to be extremely efficient. By not experiencing losses when going from DC to AC and back to DC, you can maximize your pumping while minimizing your power use. The most efficient way to use a solar pump is PV-direct, powering the pump directly off the solar panel, without using batteries. Rather than experiencing losses through storing power in batteries, the water itself is stored in a cistern or tank to be used when needed.

Harvest solar pump controller is a dedicated pump controller that is design especially for the power supply of solar panel. Harvest solar pump controller adopts a Power Point Tracing and proven motor drive technology to maimie power output from solar modules. This product supports both and a power inputs.When solar power is insufcient, the controller can be switched to a backup A power supply such as a generator or battery. Harvest solar pump controller provides fault detection, motor so start, and debugging etc. It is designed to provide these features with the plug and play and easy installation.
