Welcome to my shop! Specification New DC to AC Inverter Output waveform: pure sine wave Rated output power: 2500W (please make sure the rated power is higher than the rated power of the appliance you are using) Input DC voltage: 12V/24V (not dual voltage input, please select the appropriate input voltage) Frequency: 50HZ No-load current: <2 Amp Conversion efficiency ： >90% DC voltage range: 9V-15.5V/19.5V-28V Output AC Voltage : 230V AC voltage range: 200V-240V Low voltage alarm: 10V DC±0.5V Low voltage shutdown: 9V DC±0.5V Overload: shut down output Overvoltage shutdown: 15.5V USB output: 5V Overheat: Auto shutdown output Fuse: short circuit Start-up: soft start Production condition: brand new Dimensions (approx.) : 380mm*160mm*100mm Net weight (kg) : 3.5kg Colour: blue Material: aluminium alloy Socket type: EU Cooling fan: The fan stops working when the temperature is lower than or equal to 45℃; the fan starts working when the temperature is higher than or equal to 45℃. Package includes: 1. 1. inverter 2. white wireless remote control (Battery not included, 12V 23A battery is recommended) 3. Battery cable 4. user manual Please note 1. Make sure the power rating is higher than the device you want to use. 2. If you are going to run more than one device at the same time, refer to the total power. 3. If you are going to run an inductive load application for an extended period of time, select the pure sine wave inverter (blue). (May not be suitable for coffee machines). 4. Please use the standard battery cable we sent, otherwise full power output may not be guaranteed. The spare fuse in the package is only for use if the original fuse is blown accidentally. 5. Please do not connect the inverter to the grid power supply, and also prohibit the positive and negative terminals to be reversed. 6. Do not overload. Such as refrigerators, freezers, electric drills, washing machines, water pumps, microwave ovens, ovens, hoovers, hairdryers and other electrical appliances with motors inside. Troubleshooting: The inverter does not respond: 1. the connection between the battery and the inverter is not correct, please reconnect. 2. Battery polarity is reversed and fuse is blown. Replace the fuse. Low output voltage: 1. overload, load current exceeds rated current, turn off part of load and restart. 2. Input voltage is too low. Make sure the input voltage is within the rated voltage range. Low voltage alarm: 1. the battery is dead and needs to be recharged. 2. if battery voltage is too low or contact is poor, charge battery, check battery terminals or clean terminals with a dry cloth. No output from inverter: 1. if battery voltage is too low, charge or replace battery. 2. if the load current is too high, please turn off part of the load and then restart the inverter. 3. the inverter is over-temperature protected. Let the inverter cool down for a while and place it in a ventilated area. 4. If you cannot start the inverter, restart it. 5. if the terminals are reversed and the fuse is blown, replace the fuse.
