The SMA SB5.0-1 SP-US-41 Sunny Boy will work with a 2070 Watt solar array. This inverters Minimum DC Voltage / Start Voltage is 100V in 208V system or 125V in a 240V system and a Maximum DC Voltage of 600V. To determine if your array meets this requirement, look on your solar panel or datasheet for the Voc. Take 600V and divide by your Voc to arrive at the maximum number of panels you can use. Take 100V or 125V (depending on whether you use 208V or 240V) and divide by the panels Voc to arrive at the minimum number of panels you can use.
