 2. Battery mode (automatic identification) with battery low voltage protection.

 3. Battery mode output power manual adjustment function.

 upgraded the new adjustable power inverter,

 Its advantages:

 1) It adds a solar panel and battery operation mode switch.

 2) In battery mode, the knob can switch from 100W to 380W any mobilization

 3) It adds to record each time you turn off the last set of power

 The latest upgrade adjustable power inverter

 1) adds a new solar panel and battery operation mode switch (two independent mode operation, safe and reliable)

 2) rotary switch from 100W to about 370W any mobilization

 3) In battery mode, the new increase can be recorded each time you turn off the last set output power                 

                Specifications:

 PV grid-connected inverter operating mode

 The grid-tied inverter has an automated working order, without needing to monitor. On detection the power output from solar panels, device will decide if the power was large enough to begin the conversion process. Coversion process includes 5 modes, Startup, Grid-tied begin, Standby, Stop, Fault-find.

   Startup - When the start button is on, solar panel and grid lines both connected in normal condition, inverter enters working condition.

   Grid-tied begin - Grid-tied begin mode is when inverter starts to convert the Direct Current fed through from PV solar panel to a stable Alternate Current and flow to the utility grid. To enable the maximum output of energy, the device uses MPPT control technology to track sun rays, this technology promises the maximum efficiency under diferent daylight and temperature conditions.

   Standby - Standby mode is when device detects insufficient power feeding through from the solar panel, or device detects abnormal status such as voltages, frequencies, and temperatures not in the permitted range, the device enters standby mode.

   Stop - Insufficient sunlight hence insufficient PV power feeding through to the device and device enters into the standby mode, when this condition continues and DC voltages falls below 12V for over 1 minute, the device will enter Stop mode.

 When error ocurs, fault find indicator starts flashing, device will enter Stop mode. Please see 3.4 error status on LED indicator.

 Adjustable configuration panel

                Battery (battery) power output adjustment mode:

 1.the adjustable knob on the inverter to the right twist,Battery power adjustment mode opens,The right of the blue LED light on,At this point the PV inverter MPPT tracking function automatically turns off,Low output machine output power of about 100W, the adjustable knob slowly twist to the right,with the output power gradually increases, the limited battery adjustable maximum output power of about 75% of the total power of the inverter (for example, 500W inverter defined variable will be around 370W, 600W inverter will be limited to 450W)

 2. when the inverter is connected to the battery discharge the battery voltage is too low, The inverter will automatically stop to protect the battery output voltage is not too low,At this point you can not cut off the DC line between the inverter and battery,You can use other independent solar charge controller to the battery charge,When charging the battery is full,When 26 ~ 42V inverter connected to 24V battery:The inverter will automatically start and the net output (for example,Battery voltage into about 21V, the machine will automatically shut down, this time with another charge controller to the battery charge,When charged to about 25V, the machine will automatically begin to work), Charging without human intervention.
