Before you paying the order, you should see the technical parameter carefully and confirm the inverter / automatic voltage regulator / stabilizer / solar controller / transformer / uninterrupted power supplier (UPS) can meet your requirement and solve your problem.

Besides, tell me the specification and parameters of what you want to buy; the express address to calculate the shipping freight; the input voltage range and rated output voltage.

Inverter : if you want to buy, please tell us the below parameters:

Where do you need the inverter used for ?

What`s the type of the load and the total load capacity ? (xxx W /xxx KW)

What`s the input DC voltage ? (12V? 24V? or 48V?)

What`s the outputAC voltage do you need?(220V?110V?120V or 120V/240V complementary ? )

What`s the kind of your battery ? (Lead-acid? Colloidal? Lithium or others) If you used the Lithium battery, please share the battery parameters with us to matching the inverter, such as the Rated voltage, Over voltage & Under voltage protecting parameter. unless you will buy it from us.

What`s the type of your charging power ? (Utility power ? Solar Power ? Or the Generator Power ? )

If you have the solar power, do you need the related MPPT ? If yes, please share the total capacity of solar panels. (xxx W /xxx KW)

If you need the related MPPT, do you need the external single MPPT or the build-in MPPT ? (The build-in MPPT is built into the Inverter as an integrated Inverter. )

Feature of PSW7 Series Inverter&Charger
♦ High overload ability of our PSW7 charger is up to 300% rated power(20 sec)

♦ PSW7 pure sine wave inverter adopts low quiescent current, and power saver mode to reduce power consumption to 10W(3s sensing cycle)/3W(30s sensing cycle) *. It can extract max.
power from various batteries with different protections, and low voltage trip can be selected (9.5V/10V or 10V/10.5V).

♦ Uses PFC(power factor correction) for charger, which has less power consumption than conventional units.

♦ It has 15s delay before transfer when AC resumes, and overload protection when our PSW7 pure sine wave inverter equips with generator.
♦ 10ms typical transfer time between battery and AC, which guarantees power continuity of PSW7 charger. Uses selectable input AC voltage (184-253V or 154-253V) for different kinds of loads.
♦ Our PSW7 charger allows start up and through power with depleted batteries. Its powerful charge rate up to 90Amp.
♦ It can offer 3-step intelligent battery charging, and equipped with 8 preset battery type selector for totally flat batteries.

♦ LCD status display, battery/AC priority switch, USB communication port are available for our PSW7 pure sine wave inverter, it also has 17 alarms/warnings for easier operation and trouble-shooting,and ability to switch the unit on/off. In addition, select/deselect power saver mode can be used too.
