This allows users to set a threshold for the inverter to exit standby, significantly reducing energy consumption when only low-power loads are connected. The unit also boasts excellent overload capabilities, ensuring stable power delivery for various appliances. For increased power requirements, this inverter can be connected in parallel with up to three other Steca Solarix PI inverters using the Steca PA Link parallel switch box (sold separately). This enables system expansion up to 4500W nominal power. Please note that only new generation Steca Solarix PI inverters can be combined via the PA Link. Typical Applications Application Description Off-Grid Homes & Cabins Powering essential appliances, lighting, and entertainment systems in remote locations. Mobile & Recreational Vehicles Providing reliable 230V AC power for caravans, motorhomes, and boats. Backup Power Systems Ensuring critical loads remain operational during grid outages. Small Business & Workshops Running tools, computers, and office equipment from a 48V battery bank. Built-In Protection Functions The Steca Solarix PI1500-48 inverter incorporates a comprehensive suite of electronic protection functions to ensure safe and reliable operation. These include protection against over-discharge, battery overvoltage shutdown, short-circuiting, reverse polarity, over-temperature, and overload. The unit is also designed with protective insulation according to protection class II and is controlled by a digital signal processor (DSP) for enhanced reliability. It is CE and RoHS compliant, and manufactured under ISO 9001 and ISO 14001 standards. Common Questions What appliances can this 1500W inverter power? A 1500W inverter can power many common domestic appliances, including laptops, TVs, small refrigerators, microwaves (check wattage), power tools, and lighting. Always check the power consumption of your specific appliances to ensure they do not exceed the inverter's continuous or surge ratings. How does the 'sleep mode' function work? The 'sleep mode' allows you to set a load threshold. If the connected load falls below this threshold, the inverter enters a low-power standby mode (0.7W self-consumption). It will automatically 'wake up' and enter full power mode when a load exceeding the set threshold is detected, saving battery power. Can I connect multiple Steca Solarix PI1500-48 inverters together? Yes, this inverter supports parallel connection with up to three other Steca Solarix PI inverters to increase the total output power. This requires the Steca PA Link parallel switch box, which is sold separately. It is crucial that only new generation Steca Solarix PI inverters are connected in parallel. Is this inverter suitable for a 12V or 24V battery system? No, the Steca Solarix PI1500-48 is specifically designed for 48V battery banks. It has an input voltage range of 42V to 64V DC. Using it with a 12V or 24V system would be incompatible and could damage the inverter or your battery system. Installation Notes Connect the inverter directly to your 48V battery or battery bank using the supplied positive and negative cables. Ensure proper ventilation around the inverter to prevent overheating. Do not connect the inverter to 'load' terminals of a solar charge controller if the power demand is too high; connect directly to the battery. Refer to the included user manual for detailed wiring diagrams and operational instructions. Installation should ideally be performed by a qualified professional to ensure safety and compliance with local regulations. Before You Buy Verify your battery bank voltage is 48V DC. This inverter is not compatible with 12V or 24V systems. Confirm the continuous and surge power requirements of your appliances do not exceed the inverter's ratings. Consider future power needs; parallel connection requires the Steca PA Link (sold separately). Ensure you have adequate space for installation, considering the inverter's dimensions and ventilation requirements.
