Dear customer, thank you for choosing the TSOL micro inverter from TSUNESS. We hope
you will find our products meet your needs for renewable energy. Meantime, we
appreciate your feedback regarding our products.
A solar micro inverter, or simply micro inverter, is a plug-and-play device used in photo-
voltaics, that converts direct current (DC) generated by a single solar module to
alternating current (AC). The main advantage is that small amounts of shading, debris or
snow lines on any single solar module, or even a complete module failure, do not
disproportionately reduce the output of the entire array. Each micro inverter harvests
optimum power by performing maximum power point tracking (MPPT) for its connected
module. Simplicity in system design, lower amperage wires, simplified stock manage-
ment, and added safety are other factors introduced with the micro inverter solution.
This manual contains important instructions for TSOL-M350/400/800/1600micro
inverters and must be read in its entirety before installing or commissioning the
equipment. For safety, only qualified technicians, who have received training or have
demonstrated skills can install and maintain this micro inverter under the guide of this
document.
During installation, testing and inspection, adherence to all the handling and safety
instructions is mandatory. Failure to do so may result in injury or loss of life and damage
to the equipment.

Only qualified personnel should install, troubleshoot, or replace TSOL micro
inverters or the cable and accessories.
Ensure that all AC and DC are correctly wired and that none of the wires are
pinched or damaged.
When the photovoltaic array is exposed to light, it supplies a DC voltage to the
inverter.
The DC conductors of this photovoltaic system are ungrounded and may be
energized.
Always de-energize the AC branch circuit before servicing. Never disconnect
the DC connectors under load.
Do not use the equipment if any operating anomalies are found. Avoid tempo-
rary repairs.
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 are disabled.
Be aware that installation of this equipment includes risk of electric shock. Do
not install the AC junction box without first removing AC power from the
system.
Do not connect micro-inverters to the grid or energize the AC circuit(s) until you
have completed all of the installation procedures and have received prior
approval from the electrical utility company. Only qualified personnel should
connect this system to the utility grid.
Before installation, check the unit to ensure absence of any transport or
handling damage, which could affect insulation integrity or safety clearances.

All repairs should be carried out using only approved spare parts, which must
be installed in accordance with their intended use and by a licensed contractor
or authorized TSUNESS service representative. Tampering with or opening the
TSOL micro inverter will void the warranty.
The TSOL micro inverter is not protected from damage due to moisture trapped
in cabling systems. Never mate micro-inverters to cables that have been left
disconnected and exposed to wet conditions. This voids the TSUNESS warranty.
The maximum open circuit voltage of the PV module must not exceed the
specified maximum input DC voltage of the TSOL micro inverter.
You must match the DC operating voltage range of the PV module with the
allowable input voltage range of the TSOL micro-inverter.
Make sure protective sealing caps have been installed on all unused AC
connectors. Unused AC connectors are live when the system is energized by the
grid. Do not reuse sealing caps.
