Model Scope/General Description
The LMC SUN Series is an intelligent power conversion and energy storage system combining functions of solar charger,
battery charger and inverter. The LMC SUN Series Hybrid operation allows the flexibility to operate as an Off-Grid inverter
in the case of utility power loss. In contrast to single function traditional PV inverters; at normal operating conditions the
LMC SUN inverter can simultaneously feed in power back to the grid while charging the battery. The LMC SUN inverters
allow for cost efficient operation by supporting self-consumption via the battery when PV energy is low. All LMC SUN
models are equipped with a powerful and easy to use LCD controller interface and are available with adjustable charging
current feature for different battery technologies. The LMC SUN series supports a wide range of applications from
electronics, computer and server systems, common appliances to motor-based appliances and loads. The LMC Sun hybrid
PV inverter can provide power to connected loads by utilizing PV power, utility power and battery power.
