1.Q: What kind of the inverter is suitable for your appliances?
A: Pls 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,LED light), 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 3-7 times higher than your appliances.If you want to power up a refrigerator, we suggest you use 10 times higher power inverter
2.Q: Why the inverter can't be turned on ?
A: 1)Pls fully charge the battery before installing the inverter . There are some large capacitors built into the inverter, so it may be in the low-voltage protection or even unable to turn on when the battery power is low
2)As there is a soft start function, please turn on the inverter first then turn on your loads, or the output may not stable and not output normally
3)Pls check whether there is overload
3.Q: Why does the inverter automatically shut down when running loads ?
A:1). Pls check If there is a fuse or breaker installed in your system Generally,we recommend that a 300Amp fuse be installed between the inverter and the battery for the 3000watt 12volt dc version.
2). Pls check if use standard cables all . If 4 cables, please use them all, or the output will only be about a half. If you use your own cable, please make sure that the cable specification is larger than AWG 4, and if the length exceeds 24 inch, please thicken the cable .
Note that there is a voltage drop between the battery and the inverter. The thinner and longer the cable, the greater the voltage drop
3). Pls check if the battery capacity is too small .We recommend connecting to a battery system ≥ 300AH for a 3000 watt 12vDC inverter.When the DC LED reading drops while the load is running, it is likely that your battery capacity is too small to supply power to the load. Please try to add other batteries to your previous battery system.
4. Can you supply lithium battery/ solar panel as well?
Yes, we can supply lithium battery / solar panel which can match the inverter as well. We can be your one-stop new energy power supplier and partner.
5. Can I use this inverter to charge my batteries?
No. This inverter can only convert DC power to AC power. Please check our UPS Inverter (modified sine wave), for your options.
5. How long is the warranty period?
We usually provide at least one year wrranty period depends on different product, for some Lifepo4 (lithium) battery, we even can promise 10 years warranty period.
6. Can you accept customize the product with small order quantity ?
Yes, we can accept customize the product (apply customer's logo on) with small order quantity , for the details, please contact us by email or talk with us.
