• The solid inverter housing can protect from drops and bumps and stand up to harsh environments
• The inverter has a high-performance mute cooling fan that helps keep the inverter running at a low temperature and extend its life span
• It has over-voltage protection, over-load protection, low voltage protection, over-current protection, over-temperature protection and short circuit protection to guarantee safe use
• The inverter can convert the 12V DC stored in the battery into 220V AC power
• The solar panel absorbs light energy and converts the light energy into electrical energy and stores it in the battery (battery not included)
• The solar controller can control the charging and discharging of the battery

Specification:

• Solar panel:
• Working power: 20W
• Size: 480*280*2.5mm
• Open circuit voltage (convection): 20V
• Maximum power voltage (vmpp): 18V
• Short circuit current (isc): 1A
• Maximum power current (impp): 0.75
• Output: 12V
• Inverter:
• Startup peak power: 500W
• Continuous power: 250W
• Display: Input/output voltage
• Input voltage: 12VDC
• Output voltage: 220VAC
• Dual USB interface: 5VDC/2.1A
• Quiet current: ≤0.5A
• Conversion efficiency: greater than 90%
• Protection function: overload, overheating, high voltage, low voltage, reverse connection, short circuit intelligent temperature control, can be used for electrical appliances below 300W (excluding inductive load electrical appliances and motor products)

Note: 

• Use standard battery cables whenever possible. Otherwise, it will not output full power!
• Start the inverter. Start the machine first, then turn on the load. Shutdown: disconnect the load first, then shut down.
• It is strictly forbidden to reverse the main power supply to the output port and reverse the battery to the load.
• Do not overload household appliances such as inverters, motors, water pumps, air conditioners and other inductive loads. The rated power is multiplied by at least 3 times, and the value obtained must not exceed the inverter power.
• The inverter red light is on and a beep is heard. Check if there is an overload and whether the battery is fully charged (regardless of whether the battery is new). Charge the battery for at least 3 hours and try again.
• When the inverter is not in use, turn off the inverter switch.
• If the inverter buzzes, disconnect the load first, turn off the inverter switch, and then check the problem.
