User notice：
• Use solar panel ONLY connect to this equipment.
• This equipment is ON-GRID Micro inverter, To make it work properly, it must be connected to the power grid correctly, and the power grid is working properly, When the power grid stopped working, it will also stop generating.
• Do NOT exceed PV panel(s) voltage over the Solar Grid Tie Inverter max input voltage.（Voc＜50V）
• Do NOT exceed PV panel(s) power over the Grid Tie solar Inverter max input power.（300W/350W）• The positive and negative poles of the solar panel cannot be reversed. If you extend the solar panel cable. You need to be careful about this problem.
• Install away from direct sunlight and direct rain exposure.(Ventilated, dry, cool)
Regarding the heating problem of the inverter:
this is normal phenomenon. All electronic devices generate heat during operation. The inverter uses aluminum alloy material. Metal can conduct heat better. The inverter also has over-temperature protection if the temperature is high. Then the inverter will automatically reduce the working output efficiency. Or stop working. After cooling down, restart. It is recommended to install the inverter in a ventilated, dry and cool place.
About the upgrade of the inverter:
In order to better protect the inverter, we have upgraded the drive of the inverter. When the inverter reaches a certain temperature, it loses half of its power. When the thermal temperature drops to normal, it outputs full power again. If still unable to output full power, disconnect and reconnect.
About inverter repair：（This is a common problem of micro-inverters）
After a large amount of customer data feedback, the inverter cannot work because the DC or AC fuse is damaged. When you encounter this problem, we can send you accessories for free. And give you maintenance video instruction. You can easily replace it.（ This type of product is prone to fuse damage. After damage, you can contact us to send spare parts for replacement. This is the case for the entire market, but other businesses won't tell you.If you mind, we don't recommend buying it. )
About voltage：
The 18- 50V grid tie micro inverter will start up at 24V, after starting, the Solar Microinverters can work in 18V-39V (Vmp).Solar Panel Voc cannot be higher than 50V.
Vmp = solar panel working voltage; Voc = solar panel open circuit voltage.So don’t think that 50V is the working voltage (Vmp)
Why not use 12V solar panels? 12V panel working voltage Vmp18-20V, open circuit voltage Voc20-24V.
the 12V panel is just a starting voltage. If the sunlight is weak, the working voltage will be lower than 18V. It is easy to make the Solar micro-inverters work unstable, and the inverter will start repeatedly. It is easy to damage the Smart Micro inverter.
Recommended Solar Panel Voltage: Vmp30-39V; Voc38-46V
