ZCS Azzurro HYD 5000 ZP1 Single-Phase Hybrid Inverter
5 kW single-phase hybrid inverter from the Easy Power ZP1 series by ZCS Azzurro, the most widely used size in Italian residential applications. Accepts up to 7.500 W of photovoltaic power on 2 MPPTs and works with HV ZBT 5K at 400 V batteries from 5,1 to 20,4 kWh. 5.000 VA EPS, equal to the nominal output, with switching in under 10 ms. Integrated interface protection and DC switch-disconnector, IP65, 10-year warranty.
The Azzurro 1PH HYD 5000 ZP1 is the 5 kW size in ZCS Azzurro's single-phase hybrid Easy Power series, and in practice it is the most requested model in the range: it is the point where inverter power, the typical connection power of an already upgraded home, and the average size of an Italian residential system meet without waste.
7,5 kW of photovoltaics on a 5 kW inverter
The typical DC power is 7.500 W, 150% of the rated output. With 450 W modules, this means an array of around 16-17 panels managed by a 5 kW inverter: peak power is clipped for just a few hours on clear summer days, while mornings, evenings, winters, and cloudy days deliver much more. If the home has a heat pump or a wallbox, the excess energy is not wasted but shifted to loads or into the battery.
The 2 independent MPPTs accept one string each, with 16 A maximum current per input and a range from 85 to 520 V: two roof slopes with different exposure each operate at their own maximum power point, which on Italian existing buildings is almost always the real-world case.
In off-grid mode, the 5 kW are truly available
The storage charge and discharge power is 5.000 W, equal to the rated AC output, and the EPS output delivers 5.000 VA with 25 A, switching in less than 10 ms. This is a substantial difference compared with platforms where the battery delivers less than the inverter: here, the essential loads panel is sized based on the inverter's 5 kW and not on a lower value hidden in the storage datasheet. The manufacturer's clarification still applies: the power actually available depends on the number of batteries and the system status.
The storage system is the standard one: HV ZBT 5K high-voltage batteries at 400 V, from 1 to 4 modules for 5,1-20,4 kWh, with integrated BMS and programmable depth of discharge up to 90%.

Frequently asked questions
How many photovoltaic modules can I connect?
The stated typical DC power is 7.500 W, 150% of the rated power, and it is not an absolute limit: with 450 W modules, this is approximately 16-17 panels. The exact number depends on the module, number of strings, and site conditions, and must be checked using the ZCS Azzurro online configurator. The two MPPTs accept one string each, with 16 A per input.
With 5 kW, is an external interface panel required?
No. The interface protection is integrated into the inverter and, with 5 kW, it remains below the 11,08 kW threshold set by CEI 0-21 for the simplified procedure: no external SPI relay, interface device, or test report. The DC disconnector is also onboard, so a separate disconnector on the DC side is not required, resulting in a tangible saving on the panel.
How many kW do I have available during a blackout?
The EPS output reaches 5.000 VA with 25 A at 230 V, switching in less than 10 ms. This is the same value as the rated power, so the essential loads panel can be sized based on 5 kW. However, the manufacturer specifies that the power actually delivered depends on the number and type of batteries and the system status, meaning residual capacity and temperature.
What is the difference compared with the 6 kW model?
The output power changes, 5.000 versus 6.000 W, the maximum current, 25 versus 30 A, and the photovoltaic power ceiling, 7.500 versus 9.000 W. Dimensions, weight, compatible batteries, protections, and warranty are identical. The 6 kW is the maximum allowed in Italy for single-phase generation: above that power, the connection must be three-phase.
Can it be installed outdoors?
The protection rating is IP65 and the temperature range is from -10 to +60 °C, with power limitation above 45 °C. Outdoor installation is therefore possible, but it is good practice to avoid direct sun exposure throughout the day, which makes the electronics operate close to the derating threshold. Cooling is by natural convection and the noise level remains below 25 dB at one meter.
