2. SAFETY AND WARNINGS
1. All persons who are responsible for mounting, installation, commissioning,
maintenance, tests, and service of HYPONTECH inverter products must be suitably
trained and qualified for corresponding operations. They MUST be experienced and
have knowledge of operation safety and professional methods. All installation
personnel must have knowledge of all applicable safety information, standards,
directives, and regulations.
2. The product must ONLY be connected and operated with PV arrays of protection
class II, in accordance with IEC 61730, application class A. The PV modules must also
be compatible with this product. Power resources other than compatible PV arrays
MUST not be connected and operate with the product.
3. When designing or constructing a PV system, all components MUST remain in their
permitted operating ranges, and their installation requirements MUST always be
fulfilled.
4. Under exposure to sunlight, the PV array may generate dangerous output in DC
voltage. Contacts with the DC wires, conductors and live components in the inverter
may result in lethal shocks.
5. High voltages in inverter could cause lethal electrical shocks. Before proceeding any
work, including maintenance and/or service, on the inverter, fully disconnect it from
all DC input, AC grid and other voltage sources. There MUST be a 5-minute waiting
time after the full disconnection.
6. The DC input voltage of the PV array MUST never exceed the maximum input
voltage of the inverter.
7. DO NOT touch parts of the inverter during operation as heat will be induced and
these parts will exceed 60℃.

1. Measure the frequency and voltage of grid connection and make sure they follow the
inverter’s grid connection specifications.
2. An external circuit-breaker on the AC side (or a fuse) at 1.25*AC rated current is
strongly recommended.
3. Reliability of all earth connections must be tested and valid.
4. Before commissioning, disconnect the inverter and the circuit-breaker or fuse, and
prevent accidental reconnection.

7. START UP AND OPERATION
7.1 Safety Check Before Start Up
Please check before switching on any voltage resources connected to the inverter and
closing inverter’s DC switch:
1. Grid Voltage: Check the grid voltage at point of connection at the inverter complies
with permitted range of the inverter.
2. Mounting Bracket: Check if the mounting bracket is properly and securely installed.
3. Mounting of the inverter: Check if the inverter is properly mounted and attached to
the mounting bracket.
4. DC Connectors: Check if the DC connectors are installed correctly on terminals.
5. AC Connectors and Wire Assembly: Check if wires are assembled correctly on the AC
side and if the AC connector is properly and securely installed. Check if the AC
connector is firmly plugged into AC terminal.
6. Cables: Check if all cables are reliably connected. Check if the connections are
effective, while the insulations are undamaged.
7. Groundings: Check all groundings using multimeter and if all exposed metal parts of
the inverter are properly grounded.
8. DC Voltage: Check if the largest open-circuit voltage of PV arrays complies with the
permitted range.
9. DC Polarity: Check if the wires from DC voltage resource are connected to terminals
with correct polarity.
10. Grounding Resistance: Check if the grounding resistance of PV strings >1MOhm using
a multimeter.
After all installation and checks, close the AC circuit-breaker, then the DC switch. The
inverter will start to operate when DC input voltage and grid conditions meet the
requirements of inverter startup.
