Start Sizing from the Catalog Names
For a solar pump drive, begin with the Boray catalog names: BR600-P Solar Pump Inverter is the solar pump inverter item, while LV40-70 DC voltage booster for 220v small power pumps and LV60-90 DC voltage booster for 380v pumps are the DC voltage booster accessories.
220v Small Power Pump Systems
When the pump system is identified by the catalog name LV40-70 DC voltage booster for 220v small power pumps, that is the booster family to place beside the solar pump drive. The name includes the 220v and small power pump context, so use it for 220v small power pump applications named in the catalog.
380v Pump Systems
When the pump system is identified by the catalog name LV60-90 DC voltage booster for 380v pumps, that is the booster family to place beside the solar pump drive. The name includes the 380v pump context, so use it for 380v pump applications named in the catalog.
Pairing the Booster with BR600-P
If the solar pump drive is represented by BR600-P Solar Pump Inverter, select the booster from the two catalog-named booster families above. The pairing logic is based on the pump voltage class shown in the booster name, not on invented ratings.
Sizing Check Without Inventing Ratings
Before finalizing, confirm the actual pump, solar pump drive, and booster values from the relevant Boray catalog entries. Do not treat LV40-70 or LV60-90 as ratings by themselves; use them only as catalog identifiers for the 220v small power pump and 380v pump families.
