• A combination of a pure sine wave inverter, automatic battery charger and AC auto-transfer switch.
• Using low frequency transformer and input and output isolated design. It has strong load carrying capacity and strong impact resistance.
• Pure sine wave output: stable frequency and voltage,small ripple.
• 4-step progressive charging stages; charge voltage and charge current adjustable.
• Super low power loss with no-load and save battery energy effectively.
• Multiple protection functions, equipped with Ac and Dc input high & low voltage protection, over-current protection, overload protection, over-temperature protection, output short circuit protection and so on.
• Battery charging activation mode to avoid damage the battery that is deeply depleted when charging.
