Battery capacity compatibility: Designed for systems using up to 200Ah batteries (12V or 24V depending on model)
Charging regulation: Prevents overcharging, over-discharging, and reverse current flow into solar panels
Automatic voltage control: Adjusts charging based on battery condition
Overload and short-circuit protection: Protects the battery and connected appliances
Solar input handling: Works with solar panels and converts power efficiently for battery storage
LED or digital display (in most models): Shows charging status, battery level, and load condition
Types (commonly used with Power Nax controllers)
PWM (Pulse Width Modulation): Basic, cheaper, suitable for small-to-medium systems
MPPT (Maximum Power Point Tracking): More advanced, up to ~30–40% more efficient in converting solar energy
