Charge controllers are essential for solar setups, although commercial units can run into several hundred dollars. Designed for use with 40W to 120W 12V solar panels and lead acid batteries, this solar charge controller kit provides 3-stage charging with the option of equalisation and with MPPT (Maximum Power Point Tracking). Operation is for 12V panels and batteries, but a 24V upgrade will be available in future. Kit includes PCB, all components and case.
Features
• Suitable for 40W to 120W 12V solar panels
• 3-step charging
• MPPT (maximum power point tracking) charging
• Charge indicator LEDs
• Temperature compensation for charge voltage
• Optional equalisation cycle
• Optional 24V 80W to 240W operation upgrade
