4. Electrical connections
• Carefully assess the risks deriving from electric shocks and chemical hazards!
• 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.
• A 25A AC disconnecting device (circuit breaker) must be installed between the 1PH HYD3000-HYD6000-ZP1
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-ZP1 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
menu).
The batteries can be recharged from the excess photovoltaic production or by using the forced charge mode
indicated in the “% charge mode” section of this manual.
4.1. Attentions Before Connection
The voltage in the power conversion circuit of this product is very high. Fatal danger
of electric shock or severe burns. All electrical connections of photovoltaic modules,
inverters and battery systems must be carried out by qualified personnel. Wear
rubber gloves and protective clothing (protective glasses and boots) when operating
high voltage/current systems such as inverters and battery systems.
Attention
This product is mainly applied to photovoltaic energy storage systems for household
use. If not used according to the instructions, the protection provided by the
equipment may be damaged.
