About Microinverter
This system is composed of a group of Microinverters that convert direct current (DC) into
alternating current (AC) and feeds it into the public grid. The system is designed for the
incorporation of one Microinverter for four photovoltaic modules. Each Microinverter works
independently that guarantees the maximum power generation of each photovoltaic
module. This setup enables user to control the production of a single photovoltaic module
directly, consequently improving the flexibility and reliability of the system.

2. About Safety
2.1 Important Safety Instructions
The MI-1000/MI-1200/MI-1500 Microinverter is designed and tested according to
international safety requirements (IEC62109-1/-2, VDE4105, VDE0126, AS
4777.1 /.2& AS 3000). However, certain safety precautions must be taken when
installing and operating this inverter. 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 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 the 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 humid. 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 Hoymiles 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 caution 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.
Hoymiles accepts No liability for damage from incorrect or improper operation
Electrical Installation & Maintenance shall be conducted by licensed electrician and shall comply with
Local Wiring Rules
