TYPICAL ARRAY SIZING GUIDE

Below is a list of recommended array sizing for the MX60 for various nominal voltage batteries:

Nominal Battery Voltage

Recommended Array Size

 

(in watts, Standard Test Conditions)

12 V

800 W

24 V

1600 W

36 V

2400 W

48 V

3200 W

60 V

4000 W

The MX60 PV MPPT Charge Controller is capable of an input open circuit voltage (Voc) of up to150 VDC. Cooler climates can cause the Voc to rise above the panel Voc rating. In climates that observe temperatures less than approximately 5° F, a Voc greater than 125 VDC is not recommended.

When sizing an array, it is recommended that the nominal array voltage be higher than the nomi- nal battery voltage. Below is a list of recommended nominal array sizing:

Nominal Battery Voltage

Nominal Array Voltage (recommended)

12 V

24 V (or higher)*

24 V

36 V (or higher)*

36 V

48 V (or higher)*

48 V

60 V (or higher)*

60 V

60 V (low temp is less than 5° F) or

 

72v (low temp is greater than 5° F)

*When sizing an array to charge controller with a distance of 70 feet or greater, OutBack recommends the nominal array voltage be slightly higher than the recommended nominal array voltage. Example: A 36 VDC nominal array recharging a 12 V nominal battery with an array to charge controller distance of about 70 feet or greater. Sizing the nominal array voltage higher than the nominal battery voltage ensures that the Maximum Power Point is always above the battery voltage. The Maximum Power Point will decrease as the panels warm up, thus lowering the output of the array. The MX60 Charge Controller will not be able to boost the output if the Maximum Power Point of the array is at or lower than the battery voltage.
