This solar regulator is mounted directly to the solar panel's junction box. This eliminates the need for an additional housing for the controller. The kit also includes a removable mounting plate to mount it away from the solar panel.
It is epoxy sealed for outdoor use and certified for use in Class 1, Division 2 hazardous locations, making it an ideal controller for solar powered oil/gas applications.
Available in a 6 amp or 12 amp versions;
- 6A for solar panels up to 85 watts
- 12A for solar panels up to 170 watts
- High Reliability - Rated to 70°C to operate in high temperatures at the solar module. More reliable than controllers mounted inside the junction box. Uses very low on-resistance power MOSFET’s. No need to re-rate
- Outdoor Rated - ETL approved for outdoor use without an additional enclosure. Rugged IP65, UV resistant case. Epoxy encapsulated printed circuit board and watertight connection to the module junction box.
- Extensive Electronic Protections - Fully protected against reverse polarity, short circuit, overcurrent, lightning and transient surges, high temperature and reverse current at night.
- Longer Battery Life - Series PWM with 3 stage charging: bulk, PWM regulation and float. Includes temperature compensation at the controller or alternatively at the battery when using optional remote temperature sensor. Able to charge a zero voltage battery.
- Rated for Hazardous Locations - Specifically designed for solar power systems in the oil/gas industry. Approved for use in Class 1, Division 2, Groups A,B,C,D.
- Easy to Install and monitor - Fits standard half inch conduit knockout (PG 13.5, M20) in module junction box. It can also be mounted seperately using the included mounting plate which is removed when attaching to a junction box, both methods fasten with included locknut.
- Wires have fork connectors for easy connection to solar module terminals. Bi-color LED is easy to read from the ground when the solar module is pole-mounted. Indicates solar charging, regulation, normal nighttime operation and any controller or system faults.
