Introduction

1.1 Important Safety Instructions

Danger!

• Danger to life due to high voltages in the inverter!
• All work must be carried out by qualified electrician.
• The appliance is not to be used by children or persons with reduced physical sensory or mental  capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.
• Children should be supervised to ensure that they do not play with the appliance.

Caution!

• Danger of burn injuries due to hot enclosure parts!
• During operation, the upper lid of the enclosure and the enclosure body may become hot.
• Only touch the lower enclosure lid during operation.

Caution!

• Possible damage to health as a result of the effects of radiation!
• Do not stay closer than 20 cm to inverter for any length of time.

Note!

• Grounding the PV generator.
• Comply with the local requirements for grounding the PV modules and the PV generator. It is recommends connecting the generator frame and other electrically conductive  surfaces in a manner which ensures continuous conduction and ground these in order to have optimal protection of system and persons.

Warning!
Ensure input DC voltage ≤Max. DC voltage .Over voltage may cause permanent damage to inverter or other losses, which will not be included in warranty!

Warning！

• Authorized service personnel must disconnect both AC and DC power from inverter before attempting any maintenance or cleaning or working on any circuits connected to inverter.
• Risk of electric shock!
• Accessories only together with the inverter shipment are recommended here.Other wise may result in a risk of fire, electric shock, or injury to person.
• Make sure that existing wiring is in good condition and that wire is not undersized.
• Do not disassemble any parts of inverter which are not mentioned in installation guide. It contains no user-serviceable parts. See Warranty for instructions on obtaining service. Attempting to service the inverter yourself may result in a risk of electric shock or fire and will void your warranty.
• Keep away from flammable, explosive materials to avoid fire disaster.
• The installation place should be away from humid or corrosive substance.
• Authorized service personnel must use insulated tools when installing or working with this equipment.
• PV modules shall have an IEC 61730 class A rating.
• Never touch either the positive or negative pole of PV connecting device. Strictly prohibit touching both of them at the same time.
• The unit contains capacitors that remain charged to a potentially lethal voltage after the MAINS , battery and PV supply has been disconnected.
• Hazardous voltage will present for up to 5 minutes after disconnection from power supply.
• CAUTION-RISK of electric shock from energy stored in capacitor, Never operate on the inverter couplers, the MAINS cables, Battery cables, PV cables or the PV generator when power is applied. After switching off the PV , battery and Mains, always wait for 5minutes to let the intermediate circuit capacitors discharge before unplugging DC , battery in plug and MAINS couplers.
• When accessing the internal circuit of inverter, it is very important to wait 5 minutes before operating the power circuit or demounting the electrolyte capacitors inside the device. Do not open the device before hand since the capacitors require time sufficiently discharge!

1.3 Basic features
BD series hybrid inverter is a high quality inverter which can convert solar energy to AC energy and store energy into battery.
The inverter can be used to optimize self consumption, store in the battery for future use or feeding to public grid. Work mode depends on PV energy and user’ s preference. It can provide power for emergency use during the grid lost by using t h e energy from battery an d in verger (generated from PV).In addition, the parallel function is available(off grid model).

1.4 Work Modes
Hybrid Inverter provides multiple work modes based on different requirements.
Work modes: Self-use

	1.When PV, Grid, Battery is available: A. Solar energy provides power to the loads as first priority, if solar energy is sufficient to power all connected loads, solar  energy excess power will provides to charge battery, and then redundant power will feed to grid.
	B. Solar energy provides power to the loads as first priority ,if solar energy is not sufficient to power all connected loads,  battery energy will supply power to the loads at the same time.
	C. Solar energy provides power to the loads as first priority ,if solar energy and battery are not sufficient to power all  connected loads, utility energy (Main Grid) will supply power to the loads with solar energy at the same time.
	2 .When PV, Grid is available（without battery): A. Solar energy provides power to the loads as first priority ,if solar energy is sufficient, the excess power will feed to grid.
	B. Solar energy provides power to the loads as first priority, if solar energy is not sufficient to power all connected loads, Grid  energy will supply power to the loads at the same time.
	3 .When PV, Battery is available Grid is disconnected): A. Solar energy provides power to the loads as first priority ,if solar energy is sufficient to power all connected loads, solar  energy will provides to charge battery.
	B. Solar energy provides power to the loads as first priority ,if solar energy is not sufficient to power all connected loads,  battery energy and solar energy will supply power to the loads at the same time.

Work modes: Peak shift

	1.When PV, Grid, Battery is available: A. On charge time, solar energy will charge battery as first priority. The excess energy will supply power to the loads. If solar  energy is sufficient to supply loads and charge battery, and If there’s still some extra energy, then the excess power will feed the power to grid
	B. On charge time, solar energy will charge battery as first priority. Then the excess solar energy will supply power to loads. If  solar energy is not sufficient to charge battery and supply loads, grid will supply all the connected loads with solar energy together.
	C. On discharge time, solar energy provides power to the loads as first priority, if solar energy is sufficient to supply loads ,and  if there’s still some extra energy from solar energy ,then the excess power and battery will deliver the power to the grid at the same time.
	D. In the period of no charge or discharge, the solar power supply loads at first priority , excess energy to the grid.
	2. When Grid, Battery is available(PV is disconnected): A. On charge time, grid will charge battery and supply power to the connected loads at the same time.
	B. On discharge time, if load power is less than battery power, battery will supply power to loads as first priority, the excess power will be feed to grid.
	C. On discharge time, if load power is more than battery power, battery and grid will supply power to the loads at the same time.

Work modes: Bat priority

1. When PV, Grid, Battery is available: A. Solar energy will charge battery as first priority, if solar energy is excess, the excess power will supply load. If there’s still some  extra energy, then the excess power will feed the power to grid . B. Solar energy will charge battery as first priority, if solar energy is excess, the excess power will supply load. If solar energy is not  sufficient to charge battery and supply loads, grid will supply power to loads. 2. When Grid, Battery is available（PV is disconnected): Grid will supply power to load and charge battery at the same time.

Note!
If set anti-Reverse function allowable, Once on the work mode of Self-use Peak , shift, battery priority, the system will not feed power to grid.
