Re: 13 panel string putting out just over 200% of what 4 of the same panels put out.
The specs MPPT OPERATING VOLTAGE RANGE 140-500 VDC NOMINAL MPPT VOLTAGE 360 VDC Startup is 100 vdc minimum... No problem. Typical worst case mppt voltage6 x 34 vdc Vmp x 0.81 hot panel derate = 165 V…1 · -
Re: Max watt harvest with 400w array
In general, the Vmp-array voltage with a MPPT type charge controller should be around 100% (cool day) to 80% of the Vmp-array-standard temperature voltage (cold temperatures, Vmp/Voc rise... Hot sola…1 · -
Re: 13 panel string putting out just over 200% of what 4 of the same panels put out.
Three bad panels sound about right... You could lose upwards of 30-40 volts per "dead" panel... Your present Vmp-array is something like 100-120 VDC "less" than I would have expec…1 · -

Guessing that JHB is Johannesburg, South Africa... Without knowing anything about your system, I would expect the maximum output on a warm/clear/around solar noon day, that your array would max out a…1 ·
