pure sine wave 220v dc to ac 20000 watt inverter 3phase 380v
pure sine wave 220v dc to ac 20000 watt inverter 3phase 380v
The range of COSUPER TPI inverters is designed to meet power requirements in locations not covered by the grid or where electricity is very expensive.
The main feature of TPI inverters is that they are capable of generating electricity from Batteries to create 3-phase power to operate the appliances.TPI inverters are designed with three-phase balance technology to allow three-phase inverters give single phase power. With the low-frequency technology, TPI has better operating performance and stability, especially on inductive loads. Three phase balance supports both single phase and three phases at the same time

Q 1. How's the delivery time?
A. usually it will take about 15 days for production
Q 2. Tell me the standard of the package?
A. For the small capacity, it uses carton, but for big capacity, we should use strong wooden case for protection.
Q 3. What kind of material of the transformer?
A. 100% copper
Q 4.Would you accept to use our logo?
A. If you have good quantity, it absolutely no problem to do OEM.
Q 5. We want to know month capacity.
A. It depends on which model. For example for relay type small capacity, month capacity can reach near 20000pcs and big capacity near 3000pcs.
Q 6. Does the inverter connect with the solar system?
A.Yes.Because of the unique feature which combines invert, charger and AC auto-transfer switch into one complete system, made inverter not only connect with the solar system, also could be used in& officer equipment, household items, power tools and etc..
Q7. what kind of certificate you have?
A. Our company already achieve CE FCC PSE RHOS.
