Product Category	Hyibrid Inverters, Inverters
Brand	Solax Power
PhasesDescribes the electrical phase configuration—Single-phase for residential use, Three-phase for commercial or industrial systems, and Split-phase common in North American households.	Three PhaseCommercial and industrial power standard with 400 V three-phase supply.
Rated Power [W]Indicates the maximum continuous power output or input the device can handle under standard operating conditions, measured in watts (W).	30 kW
Nominal AC Power [W]Nominal AC power refers to the rated output power of an inverter in alternating current (AC) form under standard operating conditions. It is usually expressed in watts (W) and represents the maximum continuous power an inverter can supply to an AC load without causing any damage or operational issues.	30kW
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.	400V
Nominal Current [A]Nominal current is essentially the normal electrical current that we would expect to flow through a circuit at any given time.	43.5A
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
Inverter TypeAn inverter type refers to the specific technology and functionality of a solar inverter. The main types include grid-tied, off-grid, and hybrid inverters. Each serves a different purpose:	Hybrid, On-Grid (Grid Tie)
Max. PV array input power [Wp]The PV array power is the maximum power of the PV modules connected to one PV inverter.	60000W
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).	30000
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.	200V
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.	1000V
MPPT Voltage Range [V]The MPPT (Maximum Power Point Tracking) voltage range refers to the range of input voltages at which an MPPT solar charge controller or inverter can operate efficiently to optimize the power output of a solar panel or array.	160V – 950V
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.	3
No. of PV StringsThe 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.	6
Battery Type	High VoltageEfficient large-scale battery technology operating above 400 V DC., Lithium Iron Phosphate (LiFePO4) – LFPLithium Iron Phosphate (LiFePO4) batteries are one of the most reliable and safest energy storage solutions for solar systems. Known for their long lifespan, high efficiency, and superior safety, these batteries are a top choice for residential, commercial, and off-grid solar storage.
Battery Voltage Range [V]Indicates the allowable DC voltage window in which the solar battery or energy storage system operates safely. Ensure compatibility with the selected solar inverter and hybrid inverter input voltage range.	180 V – 800 V
Max. Charge & Discharge Current [A]The maximum charge and discharge current refers to the highest current a battery or energy storage system can handle safely during charging and discharging processes. It is an important parameter that helps ensure the battery operates within safe limits and prevents damage, overheating, or other safety hazards.	60 A
CommunicationSpecifies how the device communicates with other systems or networks—options include RS485, CAN, LAN, Wi-Fi, 4G, and Optical for data exchange and remote monitoring.	RS485, WIFI
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.	IP66Completely 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.
WarrantyNormally 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
