4kw Sine Wave Renewable Electric Power Inverter

ORO POWER pure sine wave charger inverter with CE SGS Approved, OEM/ODM accepted

(1): Description of the diagram
A, Give priority to the use of AC
Step1: When commercial power input is normal, AC power the load directly and recharge battery.

Step2: When commercial power shut off, the system will switch to give priority to the use of DC in 5ms automatically, ensuring normal working.

Step3: When commercial power is recovery, system will switch to give priority to use of AC and recharge battery.

B, Give priority to the use of DC
Recharge battery mainly from solar energy, commercial power assist recharging.

Step1: When commercial power is normal, voltage of battery higher than 11V, DC turn into AC through inverter and power load.

Step2: When the voltage of battery is lower than 11V, the system switch to commercial power automatically and recharging battery.

Step3: When the voltage of battery up to 13.5V, system switch to photovoltaic power and power the load.

Step4: When both commercial power and photovoltaic power broke down, battey will shut off with voltage lower than 10v
If commercial power is normal, AC will power load and recharge battery.

If commercial power still broke down, photovoltaic power recharge battery until voltage up to 12v and turn on with conversion mode.


(3): Intelligent charge
1) Charge different kinds of batteries, refer to the parameter of product(fifth of this manual)
2)Three charge stages
Stage 1: The charger will run at full current in CC mode until the charger reaches the boost voltage. Activate battery, promote power. (Boost CC Stage)
Stage2: The charger will keep the boost voltage in Boost CV mode. Give battery enough time to absorb energy, protect battery and electrode form over charge, extend life time. (Boost CV Stage)
Stage3: When the battery is full, It will turn into float voltage automatically to keep full power and check battery power all the time, stop working when charge finish to save power. (Float Stage)


(4)Power save mode(detect time is 5s): When boot under this mode, no load power consumption is 1w-6w, only CPU works, It will detect system cyclically, when load more than 30w, system will boot and enter normal working mode, power load in5s, when load is less than30w, It will enter energy-saving mode in5s. This mode save unnecessary power.

(2). Characters:
1. Pure sine wave output. Built-in transfer switch automatically transfers between inverter power and incoming AC power

2. CPU management, intelligent control, module design

3. LED/LCD display function

4. High conversion efficiency (between 90%-98%), low consumption

5. Can match with various battery types, such as sealed lead acid battery, open lead acid battery, gel battery and different types of lithium batteries.
Three-step intelligent charging mode available.
-Able to charge various types of battery
-Maximum charging current is adjustable
-Can be use as a charger

7. Also called a dynamic inverter, due to the advantage of having a powerful overload capacity. For example, 1KW model can power 1P air conditioning. 2KW can power 2Ps of air conditioning, 3KW can power 3Ps of air conditioning, etc.

8. With adopting the latest American low frequency circuit design and new electric materials, the whole system is more stable, with a low malfunction rate and long-life. Under normal usage, product life expectancy is 8 years.

9. Protection: High voltage protection
Under-voltage protection
Over-temperature shutdown
Automatic overload protection
Short-circuit protection

10. Power efficiency designing, resisting harmonic wave and inductive load, safe and stable.

11. The frequency of 50/60HZ automatic selection, give priority to use AC and DC with automatic adjustment. Display dynamic schematic diagram, comprehensive functions. Easier to use.
