1. How to choose a suitable power of inverter?
For resistive load (TV, computer, fans, lights, lamps, water heater) please choose inverter higher than its rated power. For example, for 800w cooker please choose 1000W inverter.
For inductive load ( refrigerator, A/C, pump, motor, compressor, pumps, microwave, washing machines and so on), there surge power can be 3-7 times higher. Please choose the power inverter with the power of 5-10 times or higher. For example, we would recommend 2000W inverter for 1 HP air-condition (735W).
2. Can I use Connect this inverter in Parallel to afford higher load, for example connect 2x2500w inverter in parallel to build a 5000w Inverter?
No, it can only be used signally and within 3500W ( its rated power range).
3. Does this inverter has a charger inside?
No, this item only provides 12V to 120V conversion, don't have a built-in charger inside, cannot be used to charge your battery.
4. Can this inverter work with Lithium batteries?
Yes, as long as its voltage is within 10-15V. And it compatible with most batteries on the market.
