Features

●Adjust the usage mode, take priority of PV or AC according to the status of configuration and sunlight source.

●Chose the PV system charge current on base of capacity of the battery accordingly.

●Independent MPPT control micro-controller system maximized the power pint of PV battery, realize battery charging and parameter management .

●Use advanced SPWM modulation technique ,high speed power MOS, use independence transformer voltage step-up technique and though LC filter ,it can provide standard sine wave

●voltage to the loads, meanwhile reduce the noise jamming to the load.

●LCD display every operating parameter and state of products.

●MPPT control system adapt PWM modulation technique, enables it sustain the PV’s Max. open-circuit voltage.

●AC input and high efficiency online synchronous voltage stabilizing technology, input 165~275Vac, safety operation, greatly decrease the battery’s use frequency, prolong life-span of the battery.

● When PV time is not long enough and without AC ,the battery will supply power to loads. While if battery is going to used up, system start urgent beep alarm, frequency is 0.2s, to notify the workers that battery has used up, AC power would be connected in.if not, the system will shut off automatically to protect the battery.

●Initial stage of PV battery supplying power, it gives sound alarm in every 5s,and stop after 40s

Automatically, won’t disturbing working environment.

●When the battery is going to be used up, system start urgent alarm again in every 0.2s,to remind the workers that battery will be used up ,system will be shut off.

●Normal overload: it alarms when load exceed by 10%/25%/50%.

●Short circuit protection: once inverting out suffer instantaneous shocks or short circuit, equipment will limit the output current, the system will be shut off automatically if it lasts for 10ms.

●Smart no-load automatic shut off technology.

●When the battery (or solar energy) supply power ,the system test load automatically, if the load less than 5%,it will be defined as no-load state, in order to reduce the power loss, system will turn off inverting output in one minute under no-loading state.

●Optional: system connect grid power with frequency of 50Hz/60Hz, system will test grid power frequency, and will provide the same voltage frequency(50Hz/60Hz) upon the outage of grid power.
