ZK-SJ30 700W 30A Solar MPPT Boost Power Module for Battery Charging

ZK-SJ30 700W Automatic Buck-Boost Power Module

The ZK-SJ30 is a high-power DC-DC buck-boost module with adjustable constant-voltage and constant-current control. It can step voltage up or down within its operating range, making it useful for bench power, LED driving, battery-charging projects, and solar input experiments.

Electrical Ratings

• Input voltage: 6-80V DC.
• Output voltage: 1.3-78V DC, adjustable.
• Listed maximum power: 700W.
• Listed maximum current: 30A.
• Control modes: adjustable constant voltage (CV) and constant current (CC).

Functions

• Automatic buck-boost conversion when the input voltage is above or below the target output voltage.
• Adjustable voltage and current limits for power-supply, LED-driver, and battery-charging experiments.
• Solar input operation with adjustable tracking-point voltage for matching a panel's operating point.
• Heatsinking and forced-air cooling hardware on the module for high-load operation.

Choose the Correct Option

• Without Display: power module without the plug-in LCD display.
• With display: includes the display version shown in the product images for visual readings and setup.

Important Use Notes

• 700W and 30A are maximum ratings. Continuous output depends on input source capability, voltage difference, airflow, wiring resistance, and thermal conditions.
• Use suitably rated cables, terminals, fusing, and an enclosed installation. Do not handle the board while powered.
• For battery charging, set the voltage/current limits for the exact battery chemistry and use an appropriate battery-management and protection system.
• The solar tracking adjustment is a module feature for projects; this board is not a complete certified solar charge controller.

Mechanical Details

• Approximate board size: 110 x 93.5 x 46mm.
• Mounting-hole spacing: approximately 105 x 84.5mm; hole diameter approximately 3mm.
