The specifications for the diode follow:
• a power diode
• rated equal or greater than 80 volts
• rated equal or greater than 10 amps (SW-10CL) or 20 amps (SW-20CL) or 30 amps
(SW-30CL)
For large inductive loads, a heat sink for the diode may be necessary.
General Load Control Notes
In addition to the inductive loads discussed above, there are a few other load issues that
require attention:
Inverters
Inverters should never be connected to the SunWide
Reverse Polarity
If the battery is correctly connected (LEDs are on), the load should be connected very
carefully with regard to polarity (+ / –).
If the polarity is reversed, the controller cannot detect this. There are no indications.
Loads without polarity will not be affected.
Loads with polarity can be damaged. It is possible that the SunWide will go into short
circuit protection before the load is damaged. If the LEDs indicate a “Fault”, be certain to
check for both shorts and reversed polarity connections.
If the controller does not go into short circuit protection, the loads with polarity will be
damaged.
CAUTION: Carefully verify the polarity (+ and –) of the load connections before
applying power to the controller.
