UPower inverter /charger combines with solar & utility charging and AC output in one unit, which adopts a multi-core processordesign and advanced MPPT control algorithm to realize intelligent management. The device is usually used in remote area where islack of reliable utility but rich of sun shine.
UP as reliable industrial standard equipment has quick response speed and excellent high transfer efficiency.
Intelligent adjustment of total charging current from both solar and utility, automatic adjustment is realized via different workingmodes selection, which ensure to provide power energy supply maximally.
The PV charging module adopts the up-to-date optimized MPPT tracking technology, it can quickly track the maximum power pointof the PV array in any environment even has the multi crest tracking ability. The MPP tracking speed and energy transfer efficiency isquite high. The PV and AC charge current can be adjusted manually, which can meet total charge current limit, and PV& utility chargecurrent ratio distribution. Full electronic protection functions are available.
The AC-DC charging module adopts the advanced MPPT control algorithm, realize fully digitalized double closed-loop control forvoltage and current, with high reliability and response speed. With wide AC input voltage range and charge current limitation volumecan be set. This module has complete protection functions at input and output.
The DC-AC inverter module is based on full digital and intelligent design. It adopts the advanced SPWM technology, outputs the puresine wave and converts 24/48VDC to 220/230VAC, which is suitable for AC loads of household appliances, electric tools, commercialunits, electronic audio and video devices etc.
With Utility by-pass charging function, the utility module can provide power supply to loads directly, and charge the batterysimultaneously. Under utility charge status, user can choose by-pass mode or inverter output mode. This characteristic is prefered inthe area where the utility is not stable,user should choose inverter output mode to get stable output voltage to avoid the appliancedamaged because of bad condition utility.
The display module is key for communication. The 4.2 inch LCD display presents system status and real time data, user can set workparameters easily the 4 buttons.
