How to compare Nastec-class bids without brochure wars
When tenders mention “nastec inverter”, freeze electrical and hydraulic scope first: motor kW/voltage/phase, PV Voc/Vmp, IP, hybrid AC, dry-run/tank logic, warranty and lead time. Only then compare brands. Boray will map BR500-P / BR600-P / FD600 to that scope and will not invent competitor specifications.
Equal-scope checklist for the purchase order
Copy these lines onto every bid — including alternatives to “nastec inverter”: rated current, PV input window, overload, enclosure, pump protections, documentation language, and Incoterms. Reject “similar to” claims that omit frame numbers.
Where Boray sits as a manufacturer alternative
Boray is a Shenzhen manufacturer of solar pump inverters and motor-control products. Use Boray when you need a documented solar pump VFD response beside a “nastec inverter” line item. Boray does not claim to be that brand; it competes on verified scope and engineering support.
Replacement and migration notes
If you are replacing an installed unit found via “nastec inverter” searches, capture motor plate, PV string data and protection settings before rip-out. Match voltage/current; re-commission dry-run and tank inputs. Parameter menus are never identical across brands.
Next step with Boray
Send the ratings from the “nastec inverter” quote (kW, voltage, IP) plus your motor and array data. Focus: Identify exact line item; add Boray as drive alternative on documented head/flow/PV scope.
