1. Structure of Off-Grid Low Frequency PV Inverter Description
A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a
utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a
critical BOS–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar inverters have special
functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection..
2. Main Features of the Off-Grid Low Frequency PV Inverter
• High overload ability of our EP3200 charger is up to 300% rated power
• EP3200 pure sine wave inverter adopts low quiescent current, and power saver mode to reduce power consumption to 3W
• It can extract max• power from various batteries with different protections, and low voltage trip can be selected (10V/10. 5V/11V)
• Uses PFC (power factor correction) for charger, which has less power consumption than conventional units.
• It has 10s delay before transfer when AC resumes, and overload protection when our APC pure sine wave inverter equips with generator
• 10ms typical transfer time between battery and AC, which guarantees power continuity of EP3200 charger. Uses selectable input AC
voltage (185-265V or 155-255V) for different kinds of loads
• Our EP3200 charger allows start up and through power with depleted batteries. Its powerful charge rate up to 70Amp
• It can offer 3-step intelligent battery charging, and equipped with 6 preset battery type selector for totally flat batteries
• LCD status display, battery/AC priority switch, RS232 communication port are available for our EP3200 pure sine wave inverter, it also has
17 alarms/warnings for easier operation and trouble-shooting, and ability to switch the unit on/off. In addition, select/deselect power saver
mode can be used too
