Powmr 5.5KW PV 500VDC Grid Output 230VAC Inverter Charger Compatibility With Lead Acid battery and Lithium Battery

Introduction

This hybrid PV inverter can provide power to connected loads by utilizing PV power, utility power and battery power.

Basic hybrid PV System Overview

Depending on different power situations, this hybrid inverter is designed to generate continuous power from PV solar modules (solar panels), battery, and the utility. When MPP input voltage of PV modules is within acceptable range (see specification for the details), this inverter is able to generate power to feed the grid (utility) and charge battery. This inverter is only compatible with PV module types of single crystalline and poly crystalline. Do not connect any PV array types other than these two types of PV modules to the inverter. Do not connect the positive or negative terminal of the solar panel to the ground. See Figure 1 for a simple diagram of a typical solar system with this hybrid inverter.

Note: To conform to the EEG standard, every inverter sold to German area is not allowed to charge battery from Utility. The relevant function is automatically disabled via the software.

Application with Energy Meter

With Modbus card II and energy meter, hybrid inverter can be easily integrated into the existing household system. For details please refer to Modbus card II manual.

Note: This application is only valid for Grid-Tie with Backup II mode. Equipped with Modbus card II, hybrid inverter is connected to energy meter with RS485 communication port. It’s used to set up self-consumption function via Modbus card to control power generation and battery charging of the inverter.

Maintenance & Cleaning

Check the following points to ensure proper operation of the whole solar system at regular intervals.

• Ensure all connectors of this inverter are cleaned all the time
• Before cleaning the solar panels, be sure to turn off PV DC breakers.
• Clean the solar panels during the cool time of the day, whenever it is visibly dirty.
• Periodically inspect the system to make sure that all wires and supports are securely fastened in place.

WARNING: There are no user-replaceable parts inside the inverter. Do not attempt to service the unit by yourself.

Battery Maintenance

• Servicing of batteries should be performed or supervised by personnel with knowledge about batteries and the required precautions.
• Replace the batteries with the same type and number of batteries or battery packs.
• The following precautions should be observed when working on batteries:

1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
3. Wear rubber gloves and boots.
4. Do not lay tools or metal parts on top of batteries.
5. Disconnect charging source prior to connecting or disconnecting battery terminals.
6. Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground. Contact with any part of a grounded battery can result in electric shock. The likelihood of such shock can be reduced if such grounds are removed during installation and maintenance (applicable to equipment and remote battery supplies without a grounded supply circuit).

CAUTION: A battery can present a risk of electric shock and high short-circuit current.

CAUTION: Do not dispose of batteries in a fire. The batteries may explode.

CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
