1.1 Overview
The UPower series is a new type of the inverter/charger combining with solar & utility charging and
AC output, which adopts a multi-core processor design and advanced MPPT control algorithm, and
has the features of high response speed, high reliability and high industrialization standard. It offers
four charging modes including Solar priority, Utility priority, Solar and Utility & Solar; two output
modes for Battery and Utility, meeting the various application demands.
The up-to-date optimized MPPT tracking technology is adopted for the PV charging modules. It can
quickly track the maximum power point of the PV array in any environment and acquire the
maximum energy of solar panel in real time;
The advanced control algorithm is adopted for AC-DC charging modules that realize fully digitalized
double closed-loop control for voltage and current, with high control precision, small volume. The
input range of AC voltage is wide, the output DC charging voltage/current is continuously
adjustable in a certain range, and the complete input/output protection functions can offer stable
and reliable charging and protection for the battery.
The DC-AC inverter modules are 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 suitable for
AC loads of household appliances, electric tools, commercial units, electronic audio and video
devices etc.
The product adopts 4.2 inch LCD display design, which real-time displays the operational data and
running state of the system. The comprehensive electronic protection function guarantees more
safe and more stable operation of the system.
