Quick Overview

Item# ECO1220
20A PWM 12V/24V Solar Charge Controller

Solar charge controller is especially designed with high-performance, efficiency and excellent quality. These controllers are designed for home solar power systems and small solar power stations.
Specially having USB charging mode. It convenience for charge 500mA loadings.
USB charging is designed for phone charging only; not designed for larger electronics like iPad, but may charge iPad slowlyTandem type PWM charging makes the charging efficiency increase by 3% to 6%, compared with non-PWM charging.Having the protection functions as overcharging, over discharging, overload, short-circuit and reversed connection.
Water proof IP22 design, protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water.
12/24V battery automatic detect.
PWM charging available,3-stage charging algorithm: impulse, bulk and float
Protection:Reverse battery pole connection protection, Lightning protection
LED display shows system status at all times.
Specially having USB charging mode

1. Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
2. The battery cable should be as short as possible to minimize loss.
3. The regulator is only suitable for lead acid battery: OPEN, AGM, GEL. It is no suited for nickel metal hydride, lithium ions or other batteries.
4. The charge regulator is only suitable for regulating solar modules. Never connect another charging source to charge.
