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.

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.

6V Series Gel/Deep Cycle Batteries 6V Series of Harvest batteries incorporate advanced VRLA&COS technology designed for ultra high rate performance in emergency light  & EPS within 5 years design at 25  degree ambient temperature. By using expanding grid and specific paste plate to insure extra durable stable performance under high rate discharge. With up-date valve related-technology and high purity raw materials, the 6V series battery has reliable standby service life. Applications Emergency Light Electric Power Supply Electric Fan Solar Garden Camping Light Electric Scale Automatic Door Aircraft Signal Railway Signal Insecticidal Lamp General Features 6V Series Battery: Capacity from 60AH to 200AH Maintenance-Free: Using oxygen recombination technology Structure: Compact design, shorter internal connectors between cells, thus low internal resistance Safety and automatic valve system: If the pressure is over 2-5psi the safety valve will automatically open and reseal. This promises  that there is no any excessive accumulation of gas in the battery

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.

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.
