No. of MPP Trackers (MPPT) An MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid via the solar inverter. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries. Maximum Power Point Tracking (MPPT) is a feature built into all grid tied solar inverters. In the simplest terms, this funky sounding feature ensures that your solar panels are always working at their maximum efficiency, no matter what the conditions. |
2 |
No. of PV Strings The maximum string size is the maximum number of PV modules that can be connected in series and maintain a maximum PV voltage below the maximum allowed input voltage of the inverter. The solar cell module is a unit array in the PV generator. It consists of solar cells connected in series to build the driving force and in parallel to supply the required current. A series-connected group of cells are called a solar cell string. |

Max. PV input voltage [V] Maximum PV voltage, which is an absolute limit of the voltage of PV panels connected in series, and “nominal PV power”. If more wattage is available from the panels, the controller won\'t use it, it will just limit the current to what it can handle. |
450V ,550V |
Max. DC PV input current [A] |
16A |
DC Startup voltage [V] The start-up voltage for a solar inverter is the minimum voltage required to initiate its operation. This voltage is crucial as it marks the point at which the inverter begins converting DC power from the solar panels into AC power for consumption. |
50V |
Max. continuous output power [VA] As a unit of measurement for electrical power, VA represents how much energy a device consumes or produces or how much current it draws from the electrical circuit. In electrical circuits, power is measured in volts (V), as well as in amperes (A). |
1210 ,1650 ,2200 ,2750 ,3000 ,3300 ,3700 ,4000 ,600 ,770 ,800 |
Nominal Voltage [V] The nominal voltage is defined as the voltage value assigned to an electric circuit or system to designate its voltage class. In simple words, the voltage level of an electrical power system is called the nominal voltage of the system. |
220V ,230V ,240V |
Nominal Current [A] Nominal current is essentially the normal electrical current that we would expect to flow through a circuit at any given time. |
16A |
Nominal AC frequency [Hz] Nominal frequency is the frequency specified by the manufacturer or supplier for a device in normal operation. 60Hz systems tend to be more efficient for longer distance transmission and are better suited for high-power applications, while 50Hz systems are more suited for low-power, local distribution. In the U.S. and many other places it is 60Hz. In Europe and many other places it\'s 50Hz. |
50Hz ,60Hz |
Protection Rating [IP] IP (or \"Ingress Protection\") ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture. |
IP66 Completely dust-tight (no ingress of dust, objects, or airborne debris permitted) Protects against splashing, falling, or dripping water. Protects against hose-directed water, from any direction, using a nozzle of 12.5 mm or smaller at higher pressures. |
Warranty Normally covers, manufacturing defects, durability issues, or equipment failure. The warranty typically covers the cost of replacing the faulty or damaged panel with a new working one. Please refer to the Warranty Documents of the product on the Manufacturer s webpage. |
10 Years |
