Product description
When the grid is normal, JKL-SMS works at on-grid mode, while the grid is abnormal, JKL-SMS will Zero switch to off-grid mode automatically
In the on-grid mode, JKL-SMS series converts the PV power to AC for loads, and extra AC to feed grid
In off grid mode, PV power converts the PV power to AC for loads, and extra AC to charge battery
