What kind of the inverter is suitable for your appliances?

Please know that load is divided into resistive load and inductive load .If you need the inverter to run the resistive load (like laptop, TV, electric cooker ), please choose the inverter with continuous power higher than the appliance’s rated power. And it is best to use 80% of the rated power. If you use microwaves,water pumps, air conditioners and other appliances with motors or compressors ,please choose the inverter whose continuous power is 3-10 times higher than your appliances.

ATTENTION:

This Power inverter is able to charge the battery bank when AC power is connected to the inverter.3000 watt is continuous output power, peak output power is 9000WThis inverter can ONLY work with 12V battery system.Inverter CAN NOT support connect in parallel.Inverter MUST have a battery, and the battery MUST be connected first

Five Woking Model:

1. AC/Line priority mode — always use ac power as priority input, provide ac output, and automatically charge the battery.

2. Battery priority mode — Priority should be given to battery power supply. After low voltage protection, the battery will be transferred to market power supply. When the battery is full, the battery will be transferred back to battery power.

3. ECO Mode—Load < 10% automatic sleep and stop output, load > 10% automatic boot back to normal inversion.

4. Generator mode — use unstable generator 120V to generate power, access the inverter AC input, through the inverter AVR regulator, automatic matching 50HZ/60HZ municipal frequency, output voltage regulator in the normal operating range.

5. Unattended Mode—When the battery is low voltage, the inverter goes into standby state(Power saving state). When the battery restores the voltage value set by yourself (such as solar charging), the inverter will restore the normal output of the inverter, and realize unattended full automatic operation!

This Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer switch. High transfer efficiency is above 90%, , complete isolate surge interference of input & output’s voltage and current, Impact resistance, super load capacity, built-in AVR stabilizer, continuous stable pure sine wave output.
Battery typesetting choose : SLA / AGM / GEL / Li-ion battery & Customize. Support lifep04，Sealed Gel AGM Flooded Lithium Batteries
Adjustable Charging Current: The max charge current can be adjusted from 0-35A, Setting the value to 0A will turn off the charging function.
Five working mode : AC priority mode / Battery priority mode / Generator mode / ECO mode / Unattended mode. When AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. When you choose battery priority, the inverter will invert from battery dc to ac output . Battery priority mode & Unattended mode have Low volt restore setting and Low volt protect setting.
Protections: Battery low voltage alarm / Battery high voltage alarm / Over temperature protection / Over load protection / Short Circuit protection. 110%-120% of the output was maintained for 30s, then the output turned to bypass, more than 160% maintained the 300ms.
