Product Description
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 two photovoltaic modules. Each microinverter works independently which guarantees
the maximum power generation of each photovoltaic module. This setup enables the user to control the
production of a single photovoltaic module directly, consequently improving the flexibility and reliability of
the system.
Manual Overview
This manual contains important instructions for the MACTM 800R microinverter and must be read in its
entirety before installing or commissioning the equipment. For safety, only a qualified technician who has
received training or have demonstrated skills, should install and maintain this microinverter under the
guide of this document.
Other Information
Product information is subject to change without notice. This user manual will be updated frequently,

2.2 Explanation of Symbols
Symbol
Usage
Treatment
To comply with European Directive 2002/96/EC on waste Electrical and
Electronic Equipment and its implementation as national law, electrical
equipment that has reached the end of its life must be collected separately and
returned to an approved recycling facility. Any device no longer required must
be returned to an authorized dealer or approved collection and recycling facility.
All operations including transport, installation, start-up, and maintenance must be carried out by
qualified, trained personnel.
Before installation, check the unit to ensure is free of any transport or handling damage, which
could affect installation integrity or safety clearances. Choose installation location carefully and
adhere to specified cooling requirements. Unauthorized removal of necessary protections,
improper use, incorrect installation/ 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 photovoltaic 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 environmental conditions such as flammable,
explosive, corrosive, extreme high/low temperature, or high humidity. Do not use the equipment
when the safety devices do not work or are disabled.
Always 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 Aptos service
representative.
Liabilities arising from commercial components are delegated to their respective manufacturers.
If the inverter has been disconnected from the public network, please use extreme
caution as some components can retain charge sufficient to create a shock hazard. Ensure all
surfaces and equipment are under touch-safe temperatures and voltage potentials prior to handling
any part of the inverter.
Aptos Solar Technology 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.

Read manual first
Please read the installation manual before installation, operation, and
maintenance.
2.3 Radio Interference Statement
This microinverter has been tested and found to comply with the limits for part 15 of FCC rules, which
can provide reasonable protection against harmful energy. However, if not installed according to
instructions, the microinverter may cause harmful interference to radio equipment. There is no
guarantee that the interference will not occur in a particular installation.
To confirm that the radio or television reception is interfered by this equipment, turn the
equipment off and on. If this equipment does cause harmful interference to the radio or
television equipment, correct the interference using one or more of the following measures:
1) Relocate the receiving antenna.
2) Increase the separation between the microinverter and the receiving antenna.
3) Place the shield between the microinverter and the receiving antenna, such as metal /
concrete roof.
4) Contact your dealer or an experienced radio/TV technician for help.

4. Product Function
4.1 Work Mode
Normal: Under this mode, Microinverter is operating normally and will convert DC power into AC
power to support the house loads and feed into the Public Grid
Zero Export Control: Under this mode Microinverter’s generation is limit base on the current house
loads, there will be no extra power feed in to the Public Grid.
Standby: There are several circumstance that Microinverter will stay in Standby mode:
- The current condition is contradicted with Microinverter operating requirement.
- No house loads or the Export control value has been set as “0” on the DTU under the Zero Export
Control mode.

5.2 Installation Precaution
Please install the Microinverter and all DC connections under the PV module to avoid direct
sunlight, rain exposure, snow layup, UV, etc. Allow a minimum of 2 cm space around the
microinverter enclosure to ensure ventilation and heat dissipation.
*Note: For some countries, the DTU will be required to meet the local grid regulation (e.g. G98/99 for UK etc.)
5.3 Space Distance Required
If the microinverters are installed on a concrete roof or steel roof, the communication with the DTU
may be slightly affected. Under such installation conditions, it is better for the microinverters to be
installed 50cm above the roof. Otherwise, more DTUs may be required to ensure communication
quality between the DTUs and the microinverters.
5.4 Preparation
Installation of the equipment is carried out based on the system design and the place in which the
equipment is installed.
