1, Pure sine wave, 48v input.
2, On-line ups.
3, Inbuilt high efficient city power/generator charger up to 65A,charging power input range 155v-265v.
4, Solar hybrid charger up to 50A.
5, Automatic cut off when fully charged 3 stages charging to maximize the protection.
6, Fully & intelligently protected (Out put short circuit, over load, in put high or low voltage,lack voltage alarm, anti polar, high temperature, etc)
Note: if you donot have electricity but only have solar panel to charge, you should always keep the switch on for the solar pannel current to come in. In case of cutting all the supply off, you can use the circuit breakers at the back to do so
