On-Off grid Hybrid Inverter Charger 12V 24V 48V for solar energy home system
UPower inverter /charger combines with solar & utility charging and AC output in one unit, which adopts a multi-core processor design and advanced MPPT control algorithm to realize intelligent management. The device is usually used in remote area where is lack 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 working modes 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 point of the PV array in any environment even has the multi crest tracking ability. The MPP tracking speed and energy transfer efficiency is quite high. The PV and AC charge current can be adjusted manually, which can meet total charge current limit, and PV& utility charge current 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 for voltage and current, with high reliability and response speed. With wide AC input voltage range and charge current limitation volume can 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 pure sine wave and converts 24/48VDC to 220/230VAC, which is suitable for AC loads of household appliances, electric tools, commercial units, 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 battery simultaneously. Under utility charge status, user can choose by-pass mode or inverter output mode. This characteristic is preferred in the area where the utility is not stable, user should choose inverter output mode to get stable output voltage to avoid the appliance damaged 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 work parameters easily the 4 buttons.
