Protect Pv PV-inverter Converts DC (Direct Current) power from PV panel(s) to AC (Alternating Current) power. Because Protect PV is grid-connected it controls the current amplitude according to the PV Panel power supply. Protect PV always tries to convert the maximum power from your PV panel(s). 3.

18 5. OPERaTiNg yOuR Pv -iNvERTER modes of operation There are 3 different modes of operation. 1. Normal mode: In this mode, Protect PV works normally. Whenever the supplied power from PV panel is sufficient (voltage>150VDC), Protect PV converts power to the grid as generated by the PV panel. If the power is insufficient, (voltage<120VDC) Protect PV enters a “waiting” state. Whilst “waiting” Protect PV uses just enough power from the PV panel monitor internal system status. In normal mode

19 • Normal operation: When PV string DC voltage is greater than 150V, Protect PV operates in the normal state. In this state, it feeds power to the grid. Protect PV automatically stops when the PV power is not enough. a. Press the “Function” key repeatedly until “Contrast” shows in the display. b. Hold the “Function” key down for more than 2 seconds, until display shows “Set contrast” and a bar graph on the right. c. Press the “Function” key repeatedly until the display’s contrast is ac

20 maximum power point trackinG (mppt) A good PV inverter must be able to convert the maximum power from any PV panel. Due to its advanced design, Protect PV PV-Inverter can track the maximum power from your PV panel in any condition. When the displayed power on the LCD output does not change dramatically, Protect PV inverter is converting the maximum power from panels. When the LCD power reading is signifi cantly changes, Protect PV is tracking the power according to the varied sunlight.
