The Wiser 1 series controllers is ideal for off-grid solar systems and allows precise control of the charging and discharging of the battery. At the same time, the low voltage disconnect function (LVD) will prevent battery damage from over discharging. 2x USB outputs (5V, 3A) adds to the flexibility of the unit.
