PWM Solar Charge Controller

30A 12/24V

The intelligent PWM (Pulse Width Modulation) system in the 30 amp solar controller will adjust the charging current to maintain the perfect voltage. This keeps your charging efficient, plus it reduces energy loss and makes for a more even charge for older regulators.

Yes. The dual USB ports give you what you need to charge small devices such as phones, GPS units, and tablets, while the 30 amp solar controller manages solar input and battery charging.

Reversed discharge protection stops energy from flowing back from the battery to the solar panels during the night or low-light conditions. This extra layer protects your battery’s stored power and prevents unnecessary strain on your system.

The 30 amp solar controller automatically detects your system’s voltage when first connected. It determines whether it’s a 12V or 24V setup and configures its charging output accordingly. No manual setup, no adjustment needed.

Yes. The 30 amp solar controller comes optimised for lithium and AGM batteries, but it can also work with a range of 12V battery chemistries. As long as their charge voltages align with the controller’s supported parameters, you’re good to go.

The regulator’s LCD display shows live system data, such as solar panel voltage, battery voltage, charging current, and load output status. LED indicators also make it easy to check charging progress and battery condition at a glance.

The 30 amp solar controller allows you to set custom voltage limits for charging and discharging. This helps stay on top of overcharge and deep discharge, extending the battery life and keeping power output consistent over time.

Programming is straightforward. Just use the touch keypad to navigate the menu, adjust voltage thresholds, set disconnection levels, or manage load timing. The system automatically saves your preferred settings once configured.

The 30 amp solar controller includes built-in electronic safeguards. It continuously monitors for short-circuits, overloads, and voltage spikes, automatically disconnecting output to prevent damage in hot, dusty, or high-vibration environments.

First, confirm all wiring is secure and correctly polarised. Check that the solar panel is in full sunlight and that all connectors are clean and tight. If inconsistencies remain, reset the 30 amp solar controller by disconnecting and reconnecting the battery.

When the battery voltage drops below the safe limit, the controller disconnects the load to stop further discharge. Once voltage recovers, it reconnects automatically. This prevents long-term damage and keeps your system stable.

These automatic thresholds are great for off-grid solar systems, caravans, 4WDs, and marine setups where power draw changes overnight. Your battery stays protected, even when the system isn’t actively monitored.
