Midnite Solar Hawke's Bay 48VDC 90A | Charge Controller | 600VDC Input

MidNite Solar Hawke’s Bay 48 VDC 90 A Charge Controller | 600 VDC PV Input is a high-voltage MPPT solar charge controller designed for 48-volt battery systems using long, high-voltage PV strings. It is intended for installations where reducing string combiner count and DC wiring complexity is a primary design goal.

The Hawke’s Bay accepts photovoltaic input voltages up to 600 VDC and converts that energy to charge a 48 V battery bank at up to 90 amps. This allows system designers to run more modules in series compared to lower-voltage controllers, which can significantly reduce balance-of-system components such as combiners, wiring, and disconnects. The controller operates as a dedicated DC-to-DC MPPT device and is not an inverter.

Key Features:

• 48 V Battery System Output: Designed specifically for 48 VDC battery banks

• 90 A Maximum Charge Current: Supports large battery capacities

• 600 VDC PV Input Rating: Enables long PV string configurations

• MPPT Charge Control: Actively tracks PV maximum power point

• DC-to-DC Controller Design: Dedicated battery charging device

• MidNite Ecosystem Compatibility: Integrates with MidNite enclosures and accessories

• Field-Serviceable Layout: Intended for installation in electrical cabinets or panels

The Hawke’s Bay controller is typically used in off-grid and hybrid systems where PV array voltage is intentionally kept high to minimize current on the PV side. This design approach improves efficiency in large systems and simplifies array wiring, particularly in ground-mount or long-run installations.

As a component, the Hawke’s Bay is best suited for system designs that already specify a 48 V battery architecture and require a charge controller capable of handling modern high-voltage PV modules without stepping down string length.
