    Carefully check the packaging and product fittings before installation. Caution Figure 3 - Installation process The 3PH HYD5000-HYD20000-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 3PH HYD5000-HYD20000-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.
