About Photovoltaic Energy StorageStep 2: Calculate the Maximum String Size. String size = 1000V / 50.87V = ~19.6. So you could have up to 19 panels in a string (rounding down to the nearest whole panel). Step 3: Verify Minimum String Size. String voltage = 37.6V * 19 panels = 714.4V. This is higher than the inverter''s minimum DC input voltage (200V), so it''s fine.
