Safety Notes
Before installation, please make sure you read & understand this manual. The HYD-ES inverter strictly comply with
safety rules of design and testing. During the installation, operation and maintenance, operators should abide by
local safety regulations. Improper operation may cause an electric shock, injury and/or damage equipments and
properties.
2.1.
Safety Notes
Electrical installation and maintenance must be carried out by competent electricians according to local rules
and regulations.
HYD-ES inverter can only be installed by qualified electrician, and only those who have appropriate certification,
as required by local authority.
Do NOT store explosives or flammable materials, e.g. gasoline, kerosene, diesel, oil, wood, cotton, or rag close
to batteries or HYD-ES inverter.
Disconnect AC connection first, then disconnect battery & PV(PV1&PV2), then wait at least 5 minutes
(discharge capacitors) before maintenance to prevent electric shock.
HYD-ES inverter shall be disconnected completely (BAT, PV & AC) while being maintained.
HYD-ES inverter can be very hot during operations. Switch off HYD-ES inverter & wait HYD-ES inverter to cool
down before maintenance.
Keep children away from batteries & HYD-ES inverter.
It’s NOT allowed to open the front cover of HYD-ES inverter. This will void the product warranty.
HYD-ES inverter damaged by improper installation/operation is NOT covered by the product warranty.
2.2.
Installation and Maintenance Notes
The battery shall be prevented from short circuit during transportation and installation.
HYD-ES inverter/batteries shall be placed in a well-ventilated place. Do not put the HYD-ES inverter/batteries in
an airtight or scarcely ventilated place or cabinet. This can be very harmful to system performance & reduce
the system life expectancy.
Keep HYD-ES inverter/batteries away from direct sunshine. Don’t put HYD-ES inverter/batteries close to a heat
source or fire. This could lead battery to leak, catch fire or explode.
The current capacity of DC power cables (from the battery to the inverter) should be at least 90A. Use short DC
power cables to avoid voltage drop & power loss.
Use a multimeter to check the battery voltage & polarity before switching ON batteries. Make sure connections
are correct according to this manual.
Use a multimeter to check the PV voltage & polarity before switching ON PV isolator. Make sure connections
are correct according to this manual.
If you want to store the batteries without using them, they should be disconnected from HYD-ES inverter, and
