1 General Information

1.1 Overview

UPower-Hi, an upgrade hybrid inverter charger, supports utility charging, oil generator charging, solar
charging, utility output, inverter output, and energy management. The DSP chip in the product with an
advanced control algorithm brings high response speed and high conversion efficiency. In addition, this
product adopts an industrial design to ensure high reliability and features multiple charging and output
modes.
The new optimized MPPT charging technology fastly tracks the solar panels' max power point in any
situation and obtains the maximum energy in real-time.
The AC to DC charging process adopts the advanced control algorithm to realize a full digital PFC and
dual closed-loop control of voltage and current. As a result, the DC output charging voltage and current
are continuously adjustable within a specific range.
The DC to AC inverting process, based on a fully smart digital design, adopts advanced SPWM
technology to get a pure sine wave output. The inverting process converts the DC power to AC power,
suitable for household appliances, power tools, industrial equipment, audio systems, and other
electronics.
The 4.2-inch LCD shows the operational status and full parameters.
To maximize solar energy utilization, users can choose energy sources according to actual needs and
flexibly take the utility as a supplement. This inverter charger can increase the system's power supply
guarantee rate, which is suitable for solar energy, utility/oil generator hybrid systems. It aims to provide
users with high-quality, high-stability, and high-reliability electrical energy.
