01BATTERIES & GENERATORS
Steady current for your off-grid setup
A compact black unit sits quietly within the electrical heart of a campervan or garden shed, managing the flow of energy from panel to battery with quiet precision.
This Portable Safety controller regulates charging for 12 or 24 volt systems, automatically adjusting voltage as ambient temperatures shift to keep your battery healthy.
02MATERIALS
Durable ABS construction for lasting service
Housed in high-quality ABS plastic, the controller resists aging and maintains its structural integrity over time. The matte black finish is practical and unobtrusive, while the casing includes four pre-drilled holes that simplify wall or board mounting without requiring extra drilling.
04PROTECTION
Comprehensive safety systems for peace of mind
Built-in safeguards include overcharge protection, short circuit protection, overload protection, and lightning protection. When battery voltage drops too low, the controller automatically cuts off the load, preserving stored energy until sufficient charge returns to the system.
05SPECS
Precise electrical parameters for reliable output
Rated for a maximum load current of 30A, the unit accepts an input range of 12–20V or 24–40V. Circuit drop remains under 250mV for charging and 50mV for discharge on loops up to one metre, ensuring efficient power transfer to your devices.

This solar charge controller is great for household power generation system.
Made of high quality ABS material, not easy to aging, safe and durable, constructed with four holes for convenient installation.
When the battery voltage is low, the controller will automatically cut off the load from the system.
Safety systems provides overcharge protection, short circuit protection, over-load protection and lightning protection.
The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.
load indicator light flashes once and will light up after 15 seconds, which shows correct
floating charging status; doesn’t light showing that charging is finished.
Before wiring please check out the rated voltage of solar panel, storage battery, load carefully, ensure they are all 12V of voltage or all 24V.
Rated current of solar panel and load can not more than the rated current of controller(30A).
Do not use light to charge solar panel, because it is insufficient when charging by light bulb.
