IVT Solar Charge Controller 12/24 V, 4 A PWM (200013)

For off-grid solar systems in caravans, boats, or cabins, the IVT Solar Charge Controller 12/24 V, 4 A regulates the charging of 12 V or 24 V lead-acid batteries from solar panels. It automatically detects the system voltage and uses PWM technology to deliver a three-stage charge (bulk, absorption, float), protecting the battery from overcharging and deep discharge.

Key specifications

• System voltage: 12 V / 24 V (auto-detection)
• Max charge current: 4 A
• Max load current: 4 A
• Charge technology: PWM
• Battery compatibility: Lead-acid (gel, AGM, flooded)
• Max solar panel open circuit voltage (Voc): 50 V
• Max solar panel power: 50 Wp (12 V system), 100 Wp (24 V system)
• Self-consumption: < 4 mA
• Operating temperature: -25 °C to +50 °C
• Protections: overcharge, deep discharge, reverse polarity (battery & solar), short circuit (load & solar), overload (load)
• Status indicators: Multi-color LED

Why choose it

This controller safeguards your battery investment with integrated protection features and a low self-consumption of under 4 mA, ensuring minimal energy waste. Its automatic voltage detection simplifies installation in mixed 12 V and 24 V systems, and the LED indicator provides at-a-glance status.

Ideal use cases

• Maintaining batteries in seasonal vehicles like caravans and boats
• Small off-grid solar setups for sheds, cabins, or remote monitoring stations
• Backup charging for 12 V or 24 V lead-acid battery banks

Good to know

The controller is designed for lead-acid batteries only and is not suitable for lithium-ion batteries. Ensure the solar panel's open circuit voltage does not exceed 50 V to avoid damage.
