Solar Cathodic Protection Units

Modern photovoltaic (solar) powered solutions from JA Electronics

allow your project to be protected by an impressed current corrosion prevention system where AC mains can not reach.


JA Electronics manufactures the Omega II® solar-powered cathodic protection controller for the corrosion prevention industry. These controllers differ from rectifiers, because they are powered by the sun’s energy rather than by commercial AC power. Some engineers call them solar cathodic protection rectifiers, because they provide power to the impressed current system in the same way as a mains-powered rectifier.

All JA Electronics solar powered solutions use the patented Omega II circuitry to provide a durable, proven Solar CP controller for system control and longevity. Since 1998, we have provided many complete solar powered cathodic protection systems and retrofit units for installation across the USA.

Reliable Kyocera® solar arrays power these units (manufacturer warranties applicable) and gel-cell batteries made specifically for solar applications insure efficient storage of solar power to protect your structures. These controllers deliver the same quality and performance that have built JA Electronics’ reputation for excellence in corrosion prevention.

Even if the majority of your project is within reach of AC mains for cathodic protection, you may be able to improve the protection of your overall system by installing one or more solar powered units in areas where commercial power is not convenient.

Solar powered protection units are supplied in base mount and pole mount varieties. The pole mount solution includes a two-piece pole and enclosure assembly for easy installation and maintenance. The pole assembly is also used as a conduit for the ground bed leads.

For installations requiring a large number of solar panels or additional batteries, a base-mount solution is also available. On all solar cathodic protection products, separate day and night output control is provided to allow reduced output at night. The two outputs may be set at any time of the day or night.

Only mil-spec components are used in our solar powered controller boards. These systems are equipped with over-current and over-voltage protection on the input and output sides, and also protected from lightning damage on the input and output sides.

All solar cathodic protection units from JA Electronics are covered by a one-year warranty against defects in components and craftsmanship.
