How to Select the Correct Solar Power System for Your Application

Solar Zone Map 1. Identify the zone your system will be installed from the map on the right.

2. Use the formula below to determine the amp hours per day your equipment requires. This is done by multiplying the operating current by the number of hours per day your equipment will be required to operate.

3. Based on the zone the solar power system will be installed and the amp hour per day requirement, use the chart below to identify a corresponding "Output Capacity" letter.

4. Use the model number charts below to locate the correct "Output Capacity"
letter and select your model number.

(Equipment Current Draw +10%) X (Equipment Run Time in Hours = Load-amp Hrs/day
0.07 + 0.007 = 0.077 (Amps) X 12 (Hrs) = 0.924 Load-amp Hrs/day

Based on this example you would pick:
Letter "A05" for Zone 5, or "B1" for Zones 3 or 4

Load-amp Hrs/day 0.5 1
Zone 1 - -
Zone 2 - -
Zone 3 B1 B1
Zone 4 A05 B1
Zone 5 A05 A05
