battery.
B
、
Give priority to the use of DC
Recharge battery mainly from solar energy,Utility Grid assist recharging.
Step1
：
When Utility Grid 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 Utility Grid 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 Utility Grid and photovoltaic power broke down, battey will shut off when voltage
lower than 10v
If Utility Grid is normal,AC will power load and recharge the battery.
If Utility Grid still broke down, photovoltaic power recharge battery until voltage up to 12v and turn
on with conversion mode.
(2): Intelligent charge
1)
Charge different kinds of batteries,refer to the parameter of product(page five 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.
(constant-current charging)
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.
(constant-voltage charging)
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 charging)
(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 ,when load is less than 30w,It will enter energy-saving mode
