【MPPT Mode】 The default setting is MPPT mode, the operation mode will return to MPPT after DC&AC restart. 【Fault Mode】 If any fault/error occurs, inverter will stop delivering power until the fault/error is rectified. Some fault/error will recover automatically, and others may need manual restart. 【Setting Mode】... -
Page 13: Installation Steps
Check the location where inverter is to be installed to ensure the following. ●The ambient temperature is within the operation range ( -20°C to +60°C -4°F to +140°F,). ●The altitude is less than 2,000 m. ● Not prone to be damaged by sea water. ●... - Page 14 Step 1: Drill holes in the wall with electrical drill according to the size of bracket (it is packed in the box). Drill straight into the wall do not shake the dril to avoid damage to the wall. Depth of the holes should be about 30mm and should be the same in all the holes.

Figure 9 Installation of Expansion Pipe Step 2: Clean all dust outside/inside the hole and ensure the distances between hole are as per requirement. Insert expansion pipes into the holes vertically, use rubber hammer to tap the pipes into the wall completely. - Page 16 1KTS 1.5KTS 2KTS 3KTS 4KTS 5KTS 6KTS 7KTS Model Max. DC voltage 500V 550 V Table 3 Max. DC Voltage of inverters Only use good quality PV cables to connect modules to inverter. Normally the voltage drop between modules and inverter could be about 1-2%. Hence inverter should be installed as close to the PV module as possible to reduce cable losses.
