This manual describes the assembly, installation, commissioning, and maintenance of the following models of Power  

microinverters: 

 

D350-M1   /   D700-M2   /   D1500-M4 

 

1.2 Target Group 

 

This manual is only for qualified technicians, who have been trained or have demonstrated skills to install and maintain 

this microinverter under the guide of this document for safety purposes. 

 

 

2.1 Important Safety Instructions 

 

The microinverters are designed and tested according to international safety requirements. However, certain safety 

precautions must be taken during installation and operation.  The  installer  must  read  and  follow  all  instructions,  cautions 

and  warnings  in  this installation manual. 

 

All  operations  including  transport,  installation,  start-up  and  maintenance,  must  be  carried  out  by qualified, trained personnel. 

Before installation, check the unit to ensure free of any transport or handling damage, which could affect insulation integrity or safety 

clearances. Choose the installation location carefully and adhere to specified cooling requirements. Unauthorized removal of necessary 

protections, improper use, incorrect installation and operation may lead to serious safety and shock hazards or equipment damage. 

Before connecting a microinverter to the power distribution grid, contact the local power distribution  grid  company  to  get  appropriate 

approvals. This connection must be made only by qualified technical personnel.  It  is  the  responsibility of  the  installer  to  provide  external 

disconnect switches and Over current Protection Devices (OCPD). 
Only one photo voltaic module can be connected to one input of the inverter. Do not connect batteries or other sources of power supply. 

The inverter can be used only if all the technical characteristics are observed and applied. 
Do  not  install  the  equipment  in  adverse  environment  conditions  such  as  flammable,  explosive, corrosive, extreme  high or  low 

temperature,  and  humidity. Do  not use  the  equipment when  the safety devices do not work or disabled. 

Use personal protective equipment, including gloves and eye protection during the installation. 
Inform the manufacturer about non-standard installation conditions. 
Do not use the equipment if any operating anomalies are found. Avoid temporary repairs. 
All  repairs  should  be  carried  out  using  only  qualified  spare  parts,  which  must  be  installed  in  accordance  with  their  intended 

use  and  by  a  licensed  contractor  or  authorized  Power  service representative. 
Liabilities arising from commercial components are delegated to their respective manufacturers. 
Anytime the inverter has been disconnected from the public network, please be extremely cautious as some components can retain charge 

sufficient to create a shock hazard. Prior to touching any part of the inverter please ensure surfaces and equipment are under touch safe 

temperatures  and  voltage potentials before proceeding. 
Power  accepts no liability for damage from incorrect or improper operation. 
Electrical Installation & Maintenance shall be conducted by a licensed electrician and shall comply with Local Wiring Rules.
