SOLAR HYBRID INVERTER SITEC 1000-H

SITEC 1000-H INVERTER is a DC-to-AC inverter with auto line-to-battery transfer and integrated charging system, serving as an extended run UPS, a standalone power source or an automotive inverter.

SITEC 1000-H INVERTER supplies power from AC power and DC source. When AC cable is connected to a wall socket, utility power goes to connected equipment(s) and/or charges the battery set via charging system. In battery mode, SITEC 1000-H INVERTER automatically converts battery energy into AC power for backing up the connected devices.

Features:

  • Automatic line-to-battery switchover
  • Selectable Input voltage ranges
  • High efficient DC-to-AC conversion, minimizing energy loss
  • Rack design & wall-mounted design for flexible installation
  • Built-in enhanced charger, selectable charger current
  • Intelligent 3-stage charger control for efficient charging and preventing overcharge
  • Auto restart while AC recovery
  • User-friendly LCD LED indications

Multiple protection: low battery alarm, low battery shutdown, over charger protection, overload protection, over temperature protection, short circuit protection

SOLAR HYBRID INVERTER SITEC 4500-H

SITEC 4500‐H is designed to serve as a backup power supply for AC loads. The input power of SITEC 4500‐H comes from PV system and AC grid which not only supply power to AC loads but also charge the battery bank when the power from AC grid or AC generator is present (also known as Line Mode).

In the event of AC grid (or AC generator) outage, the AC loads can be alternatively powered by PV system (if the illumination is sufficient) and battery bank. Please find below the system diagram of typical application.

 

SITEC 4500‐H can automatically enter 9 different operation modes depending on the status of DC input power (PV) and AC input power. Please refer to the following table for the 8 operation modes and their corresponding conditions.

AC Input GRID Power Present/ AC Input GRID Power Absent :

Strong PV Power : LINE‐PV or SOLAR‐PV / INV‐PV

Less PV Power: LINE‐HYBRID or SOLAR‐HYBRID / INV‐HYBRID

No PV Power: LINE MODE / INV MODE

No PV Load : CHARGE MODE / CHARGE MODE
