1. Introduction
The 3000SP storage inverter is an AC-connected bidirectional electrical energy inverter developed for
photovoltaic production and domestic storage systems. The system can be combined with WeCo or
Pylontech batteries offered in kit form by ZCS Azzurro. The system is also compatible with all existing
photovoltaic inverters and modules and can be integrated into an existing system or installed together with
a new photovoltaic system.
The product is equipped with an LCD display and keypad, simple and user-friendly interface that records
data on the energy produced and any errors for quick and easy assistance and support.
The 3000SP storage system is the best solution to optimise the use of energy produced by renewable
sources. The system is able to manage the bidirectional flow of electricity, while controlling the power
produced by the photovoltaic modules, the power stored and taken from the battery, the power exchanged
with the electrical grid and the power supplied to utilities.
The inverter is able to operate in different working modes: automatic, forced charging from the grid and the
possibility to charge/discharge the battery according to your needs. In automatic mode, the 3000SP inverter
is able to independently optimise the use of the renewable energy and batteries, minimising the purchase of
electricity from the national grid. The second mode forces the energy to be drawn from the grid to charge
the battery, when needed. The third option allows programming the battery discharge hours and modes,
giving the customer complete flexibility.
