SKU: APS-DS3-S
Mfg. SKU: DS3-S
Mounts on standard solar rails behind each panel, turning DC into clean 240 V AC for grid-tie systems
Two independent MPPT inputs optimize up to two panel strings—shade or mixed orientations won’t affect the rest of your array
Ideal for Canadian solar installations from B.C. to Québec
Dual PV Inputs & Independent MPPT
Tracks each string’s “sweet spot” voltage (22 V–48 V) within a 16 V–60 V range
Harvests up to 99.5 % of each panel’s potential

Solar panel voltage drops on hot summer days and spikes on cold winter mornings
To avoid over-voltage trips, keep panel Voc at least 25 % below the 60 V max—aim for about 45 V Voc
Maximize Net Metering under Ontario, Alberta, B.C. and Québec rebate programs
Slash Electricity Bills with panel-level optimization for extra kilowatt-hours
Reduce Carbon Tax by generating clean power and shrinking your grid-tied footprint
