This blocking diode kit lets you add a solar panel to a Rutland wind turbine charge controller. The diode stops current from flowing back from the battery into the panel at night. Marlec's manual for the Rutland HRDi controller requires a blocking diode on solar panels connected to its PV input, with one diode for each panel wired in parallel.

Blocking diode isolation kit includes an easily mountable diode block along with (2) 12 – 10 gauge push-on crimps and hook up instruction sheet making installation a snap. A single stainless steel screw is required for mounting (not included). Rated 25A -400V

Recommended for use with Rutland wind turbine controllers when the solar PV option is utilized.

Specifications

  • Rating: 25 A, 400 V
  • Includes: diode block, (2) 12-10 gauge push-on crimps, hook-up instruction sheet
  • Mounting: one stainless steel screw (not included)

Using it with the Rutland HRDi controller (Marlec manual)

  • The HRDi controller is designed for Rutland 50X and 91X series turbines plus up to 160 W of solar panels
  • Solar panels must be fitted with blocking diodes; panels in parallel need one each
  • Do not exceed the 160 W solar input; derate it in ambient temperatures above 40 °C
  • Cover the panels and restrain the turbine before making connections

Questions & Answers

Do I need one kit per solar panel?

If the panels are wired in parallel, yes. Marlec's HRDi manual says parallel panels should each have their own blocking diode.

How much solar can I connect to an HRDi controller?

Marlec rates the HRDi solar input at 160 W maximum, with derating above 40 °C ambient.
