SRNE ML2420: Smart 20A Solar Charging For Small Systems
Small solar setups deserve a proper MPPT controller, not a basic PWM box. The SRNE ML2420 is a 20A MPPT solar charge controller for 12V and 24V battery banks, with up to 100V of PV input. It suits cabins, sheds, RVs, boats and backup kits where every watt from the panels counts.
Why You'll Love The SRNE ML2420 Controller
More energy from your panels. MPPT tracking efficiency above 99% and conversion efficiency up to 98% help you harvest more power, especially in cool or cloudy weather.
Works with your batteries. It detects 12V or 24V automatically and supports lead-acid, lithium-ion and user-defined battery settings.
Runs your DC loads too. A 20A load output with multiple load modes, including light control and timers, can switch lights and small DC loads automatically.
Clear information. The built-in LCD screen and indicators show charging state, battery status and faults, and RS232/RS485 ports allow remote monitoring accessories.
Your life, with the SRNE ML2420 Controller
Two panels on the shed roof feed a 12V battery. During the day the ML2420 quietly charges the bank, and at dusk it switches on the yard light by itself. You only think about it when you check the screen and see a full battery.
