1. Overview

The IPB series, a high-frequency sine wave inverter, adopts a fully digital intelligent design and voltage-current dual closed-loop control algorithm. It is designed with the Utility bypass function (when the Utility is normal, the inverter output will automatically switch to the Utility bypass, i.e. utility priority). Featured with fast response, high conversion efficiency, low Total Harmonic Distortion(THD), and high reliability running, the IPB series can be widely used in the DC-AC off-grid systems (such as vehicle systems, security monitoring systems, emergency lighting systems, household power systems, field power systems, and other systems requiring higher power quality).

Features:

• Pure sine wave output
• Input to output electrical isolation
• Output power factor up to 1
• Input Protection: Low-voltage, Over-voltage
• Output Protection: Overload, Short circuit, Overheating
• RS485 com. port to realize remote monitoring①
• Utility bypass automatic switching function (utility supplies load when the utility is normal)
• External switch design, matched with EPEVER products, to expand inverter control function and reduce power consumption
• Diversified AC output sockets

① For inverters with 12V input voltage, there is no communication isolation design for the RS485/RJ11 port.

Step 2: Determine the installation location and heat-dissipation space The inverter shall be installed in a place with sufficient airflow through the dissipation pad of the inverter.
And a minimum clearance of 150mm from the upper and lower edges of the inverter is recommended to ensure natural thermal convection. The following takes IPB2000-12 as an example.

2. Battery connection

CAUTION

A fast-acting fuse must be installed on the battery side, conformed to the following requirements:
1. Fast-acting fuse voltage is 1.5 to 2 times the inverter’s rated voltage.
2. Fast-acting fuse current is 2 to 2.5 times the inverter’s rated current.
3. Distance between the fast-acting fuse and the battery cannot be farther than 150mm.

3. AC load connection

WARNING

• The AC loads shall be determined by the continuous output power of the inverter.
  The surge power of the AC load must be lower than the instantaneous surge power of the inverter, or the inverter will be damaged.

• The N pole of the AC output port cannot be grounded.

4. Connect the Utility

WARNING

• Risk of electric shock! The Utility input can generate dangerous high-voltage!
  Disconnect the circuit breaker or fast-acting fuse before wiring, and ensure that the poles’ leads are connected correctly.

• After the Utility is connected, the battery cannot be grounded. In contrast, the inverter cover must be grounded reliably (to shield the outside electromagnetic interference effectively and prevent the cover from causing electric shock to the human body).

5. Optional accessories connection

6. (Reserved) Remote switch connection

Step 4：Power on the inverter

⑴ Connect the breaker at the inverter input terminal or the fast-acting fuse at the battery terminal.
⑵ Turn on the inverter switch, and the green indicator will be lighted on, which states a normal AC output.
⑶ Connect the breaker at the AC load terminal, turn on the AC loads, and check the system working status.

CAUTION

When supplying power for different loads, it is recommended to first turn on the load with a large impulse current. And then turn on the load with a smaller impulse current after the load output is stable.
⑷ If the FAULT indicator flashes red and the buzzer alarms after powering the inverter, please immediately turn off the load and the inverter. Clear the faults according to chapter 8 Troubleshooting. After clearing the faults, please operate the inverter again by following the above steps.

6. Parameters Setting

IPB parameters such as power saving mode, baud rate, output voltage class, and output frequency class can be set by the remote meter (optional, you need to purchase it additional), phone APP, or PC software.
The following chapters take parameters setting on the remote meter as an example (for connection of the remote meter, please refer to chapter 5.3 Mounting).

6.1 Power Saving Mode
Users can enable the power saving mode and set the PSI/PSO value by the remote meter (The minimum power step is 1VA).
When the actual load power is lower than the PSI (the power to enter the power saving mode), the system will automatically switch to the power saving mode. And then, the device output is turned on for 1s and turned off for 5s.
When the actual load power exceeds the PSO (the power to exit the power saving mode), the inverter will automatically exit the power saving mode and resume work.

1. Enable power saving mode (PSE)
