3.4 Maximum Array Sizes
The following should be used as a guide to the maximum array size that can be connected to the
MPPT. The current limits to the specified level of the MPPT model so any array larger than these will
simply waste power:
Table 3.2: Maximum Photovoltaic Array Sizes in Watts
3.5 Maximum Panel Voltage (Voc) Per Battery Bank
Table 3.3: Maximum Panel Voltage per battery bank
Please remember that the Standard MPPT will
only support 150Voc per PV Panel String.
Systems should be designed for a max of
135Voc
150Voc is the absolute maximum. Systems should be designed for a max of 135Voc due to the
increase in panel voltage due to colder Panel Temperatures. Refer to your solar module
documentation for the worst-case (coldest) module temperature voltage, should provide Voc vs.
temperature data.
