SS-45C will not provide the 150% diversion load margin, and the SS-45C is only rated for
30A of source current. The SS-45C will not provide enough margin for wind gusts and
overloads, so a SS-60C should be used.
The diversion load should be sized for 52.5A (150% of the source current) up to 60A (the
rating of the SS-60C). If 55A is selected for the diversion load, the load must be capable of
diverting 55A at 30V (maximum battery voltage). If a 30V heating element is used, it would
be rated for 1,650 watts (or from 1,575W to 1,800W per the load range noted above).
If a 2,000 watt / 120 volt heating element is used, 13 of these elements in parallel will be
required for the diversion load (4.2 amps per element [Table in 6.4.4] x 13 = 54.6 amps).
The minimum diversion load would be the source output (35A) times the voltage (30V).
This would require a 1,050 watt heating element rated at 30 volts. Or if a 2,000W heater
element rated for 120 volts is used, 9 heater elements will be required to draw the required
minimum diversion load at 30 volts.
