STECA SOLARIX 1500W 48V PURE SINE WAVE POWER INVERTER 230V AC OUTPUT

 Steca Electronik, the leading global manufacturer in off-grid solar electronics. All Steca inverters are specifically designed with power loss minimisation in mind. Innovative engineering ensures that this Steca Solarix 1500W 48V pure sine wave inverter has incredibly high power conversion efficiency which significantly outperforms most other inverters. With the development, production, and testing stages conducted in their German manufacturing facility and all products supported by a 5 year warranty, Steca products are truly "100% made in Germany" to the highest European quality standards.

One of the key energy saving features of this inverter is the 'sleep mode' personalisation function. The dial on the front of the inverter allows the user to select a threshold at which the inverter will exit standby mode and enter full power mode. For example, if 'low sensitivity' is selected, the inverter will only wake up from standby mode when a high-power load is connected. This intelligent function is unique to Steca inverters and drastically minimises any energy loss from your solar system. This unit has an incredibly low standby power consumption of 0.7W and an impressive operational efficiency of up to 94%.

This product also has the unique ability to be connected in parallel on the AC output side with up to three other Steca Solarix PI inverters, offering multiple possibilities for future system expansion. In order to achieve this, the inverters will need to be linked using the Steca PA Link parallel switch box (sold separately). Adding one more inverter increases the nominal power from 1500W to 3000W, adding two inverters increases it to 4500W etc.

This product comes with important safety features including protection from over-discharge, overload, short-circuiting, over-heating and reverse polarity. The device also features a multi-coloured LED light to show system status and alert the user of any faults. The in-built automatic fan operates only when required to prevent overheating and keep noise to a minimum.

Which appliances can be powered? If you are unsure whether 1500W is sufficient for your appliances, please refer to the following table: Table of typical power consumption of domestic appliances

*Appliances marked with a star are likely to have a starting power consumption several times greater than their normal working power (typically this is caused by electric motors). This should be taken into account when choosing the correct size of inverter. For example, even though electric lawn mowers have a normal working power of 1000W, their starting power is over 4000W. This means that an inverter with a continuous power of 2000W is not suitable, because its peak power is limited to only 4000W. Always take into account the starting power requirements of your equipment - especially devices with electric motors - when choosing the right inverter.

**These appliances do not have an electric motor inside, but still have a variable power consumption with power spikes. Therefore they require a larger inverter than would be needed for other appliances with a similar nominal power rating.

Please also note: this table is provided for general guidance only. The actual power consumption of your appliances, as well as starting power requirements, may vary considerably. In all cases you will need to check the specifications of your equipment to find their continuous and starting power requirements.

If more than one device is connected to the inverter, the total power consumption should be the sum of all appliances used. This will determine the total inverter power required.

Determining the input voltage of your inverter: 12V or 24V

If you are looking for an inverter for your 12V leisure battery in a motorhome, caravan or boat, there isn't much choice in terms of the input voltage - you will need a 12V to 230V inverter, because your battery is 12V.

However, if you are building a standalone off-grid solar system (e.g. in a house, garden, shed or farm), then you can choose the voltage of your battery bank, and consequently, the input voltage of the inverter.

Instead of a 12V battery bank, you may choose to build a 24V battery bank (2 x 12V batteries wired in series will produce 24V). In this case you can use a 24V DC to 230V AC inverter, rather than 12V DC to 230V AC. This set-up will provide some important benefits:

• The input current for the inverter will be two times smaller for 24V than for 12V, making the inverter and the entire system safer and more reliable
• The cables between your battery and the inverter do not have to be as thick as those used for a 12V battery bank and inverter.

This is particularly important for large standalone solar systems with 2000W inverters. For such power levels, our recommendation is to opt for a 24V battery bank and an inverter with a 24V input voltage.
