1. HYD-ES inverter Introduction
The HYD-ES hybrid inverter is used in PV system with battery storage.
Energy produced by the PV system will be optimized for maximum
self-consumption.
The HYD-ES inverter can work in auto or time-of-use (TOU) mode, charge /
discharge the battery when needed. In auto mode, the HYD-ES inverter will charge
surplus PV energy into the battery & discharge battery to supply power to local
load when PV energy is not enough.
In case of blackout, HYD-ES inverter can work in Emergency Power Supply (EPS)
mode. HYD-ES inverter will utilize power from PV panels & energy stored in the
battery to supply power to critical load.
Caution:The inverter should not be installed in multiple inverter combinations

2. 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 or damage the
equipment and properties.
2.1. Safety Notes
Electrical installation and maintenance must be carried out by competent
electricians according to local regulations.
HYD-ES inverter can only be installed by qualified electrician, and only those
who have appropriate accreditation, as required by local authority.
Do NOT put explosives or flammable materials, e.g. gasoline, kerosene, diesel,
oil, wood slab, 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 working. 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 has been charged more than 60% before being delivered and 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 badly ventilated place or cabinet.
This can be very harmful to system performance & service life.
Keep HYD-ES inverter/batteries away from direct sunshine. Don’t put
HYD-ES inverter/batteries close to a furnace or fire. The can lead battery to leak
even explode.
The current capacity of DC power cables (from battery to inverter) should be
at least 90A. Use short DC power cables to avoid high voltage drop & power loss.
Use a multimeter to check the batter 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 be kept in a cool, dry, and ventilated
environment.
Battery maintenance operators shall have the knowledge and technical skill
for battery maintenance;
All batteries connected in parallel should be of the same model and have same
firmware version. This is a design issue needs to be considered by designer/installer,
particularly when replacing batteries or modifying an existing energy storage
system.
HYD-ES inverter is transformer-less, therefore the positive pole and negative
pole of the PV array are NOT grounded. Otherwise it will cause inverter failure. In
the PV system, all non-current carrying metal parts (such as: PV module frame, PV
rack, combiner box enclosure, inverter enclosure) should be connected to earth.
Warning: Do not disassemble or break the battery. Its electrolyte can be toxic
and damage your skin and eyes.
Warning: follow the following rules during battery installation/maintenance.
a. Take off your watch, ring, and other metal objects.
b. Only use tools with insulated handles.
c. Wear rubber gloves and shoes.
d. Do not put tools or metals above the battery.
e. Switch off HYD-ES inverter & batteries before connecting / disconnecting
battery terminals.
f. Battery positive/negative poles should be isolated from ground.
