1. Introduction
The 1PH HYD3000-HYD6000-ZSS hybrid inverter is used in photovoltaic systems with battery storage. The
system can be combined with WeCo and Pylontech batteries supplied in kit form by ZCS Azzurro.
The energy produced by the photovoltaic system will be optimised for maximum self-consumption.
The 1PH HYD3000-HYD6000-ZSS inverter can operate in automatic mode and in time-of-use charge,
charge/discharge mode. In automatic mode, when the energy produced by the PV field is greater than that
required by the utilities, the 1PH HYD3000-HYD6000-ZSS inverter charges the battery using the photovoltaic
energy in excess, and when the photovoltaic energy is lower than that required, the inverter uses the energy
stored in the battery to supply current to the local load.
In the event of a power failure (or by switching on the inverter in Off-Grid mode), the 1PH HYD3000-HYD6000-
ZSS inverter can operate in Emergency Power Supply (EPS) mode. The 1PH HYD3000-HYD6000-ZSS inverter
will use both the energy created by the photovoltaic panels and the energy stored in the battery to supply
energy to the critical load.

Use a multi-metre to check the DC polarity of the battery and cables before connecting the power supply
between the batteries and inverter.
NOTE: an inverted polarity connection may cause irreparable damage to the inverter and batteries.
Note: the Pylontech batteries, as well as the WeCo batteries do not require a disconnecting device for connecting
to the storage inverter. The Cable kit, which includes crimped power cables for connecting the Pylontech
batteries to the 1PH HYD3000-HYD6000-ZSS storage inverter, is supplied separately. Make sure your storage kit
is equipped with this accessory. In the case of WeCo batteries, the connection kit is already inside the package.
A 25A AC disconnecting device (circuit breaker) must be installed between the 1PH HYD3000-HYD6000-
ZSS inverter and the power grid. It is also recommended to use a differential with a trip threshold of 300
mA between the 1PH HYD3000-HYD6000-ZSS inverter and power grid.
For safety and proper functioning of the system, it is important to use a cable of the appropriate type and
size for the electrical connections.
- Battery connection: DC cable with cross-section of AWG8 or AWG6 (supplied).
- Grid or load connection: AC cable with cross-section of AWG12.
!!!PLEASE NOTE!!!
If the storage capacity needs to be increased by adding one or more batteries to an existing system, make sure
that all the batteries (installed and to be installed) are fully charged.
To check the charge status of each battery, connect them one at a time to the inverter and view the charge level
on the display (all the instantaneous information can be accessed by pressing the “Down” key from the main

(e.g. the negative, black one) to the last battery of the pack, as shown in the figure below. Finally, run the
batteries in parallel using the short jumpers (supplied with the battery) or those with a length of 0.6 m or
1.5 m (available on request, codes ZST-CABLE-0.6M and ZST-CABLE-1.5M), connecting respectively the
positive and negative polarities of one battery with those of the next battery.
