1.      Inverter

(1) Off grid inverter for Wind/ Solar

The off-grid inverter is a special inverter that specialized in supporting solar and wind power system. It's able to drive different kinds of loads, such as air-conditioner, refrigerator, motor, fans. And have different kinds of DC voltage optional, such as DC12V, 24V, 36V, 48V, 96V, 120V, 240V, and 360V. The off grid inverter’s power range is from 200w to 100kw.

Features of the off grid inverter

1. High transfer efficiency, highest can reach to 95%.
2. Output pure sine wave
3.Protection function completely, output short-circuit protection (take load short-circuit), overload protection, DC overload or under-voltage protection.
4. Strong ability of resist concussion, can loading all kinds of electric apparatus and industry equipments. Such as: air condition, refrigerator, television, fan, washer, fill water electric motor, tortile gate, and etc.
5.Controller and inverter integration, can not purchase controller additional .
6. The service life is long, can reach a decade.

(2)The home UPS inverter

The home UPS is one type of the off grid inverter. It usually use in the home load. And with lots of model and the function, can fix different purpose.

Features of the home UPS inverter
1.Super wide input voltage range:90V-280V
2.Four-steps AVR
3.Powerful charging current:500W up to 15A,1KW-4KW,up to 25A
4.Protection against short-circuit
5.Special overload protection, when it is overload, it will lock the unit automatically, when it restores, it will start the unit automatically again
6.when the mains come, it will start the unit automatically
7.Function that it will change its frequency instantly .it is able to drive inductive loads, such as air-conditioner, refrigerator, motor, and so on
8.With RS232,it can realize software control function

(3)Grid tie inverter/ grid connected inverter

Grid tie inverter is the core facility of solar power plant and wind turbine power plant. To assure the power plant can run stability, it highly require for the reliability of the grid tie inverter. For the curviness environment of the solar and wind turbine, the stability of DC supply is very bad, that more inquire to consummate the defensive function of the grid tie inverter and strong capability to resist all kinds of impact. The grid tie inverter’s power range is from 1kw to 500kw.

Features of the grid tie inverter/ grid connected inverter.

1, Controlled by CPU, to keep the stability of the unit.
2, Inverter grid-connected output, can follow up the utility grid in millisecond, completeness synchronization to the utility grid.
3, when utility grid test by inverter in three seconds is normal, grid-connected inverter start to work. Make sure the inverter will not damage by frequency wave.
4, it will lock the unit automatically in less than 10ms when the utility grid interrupted or over-voltage or under-voltage.
5, protectin against short-circuit and overload.
6, outout power invariablenes.(normal DC voltage)
7,when wind power or solar power shortage, DC voltage drop, grid-connected inverter output power will reduce. When DC over low achieve inverter Dc protect point, inverter will automatically lock and stop work, when DC restores, it will start the unit automatically again.
8,when wind power over-voltage(such as typhoon),or solar intensity over strong ,DC over voltage ,inverter will automatically lock itself. When DC restores, inverter will start to work automatically again.
9, communication ports:RS232,RS485,USB(optional)
10,DC to AC high transfer efficiency up to 90---96%
