This Photonic Universe 1.5kW 48V Off-Grid Power Kit is the perfect ready-to-use kit for off-grid applications requiring a reliable and constant source of power for household appliances or industrial equipment in areas without access to or without stable mains electricity. This kit can provide power to small and medium household or office appliances such as a fridge, TV, radio, lights, computer, hoover, microwave or a kettle, as well as certain high power appliances such as power tools or a washing machine. This may vary significantly according to the location and season.

The solar kit includes:

- Steca Solarix 1500W 48V pure sine wave power inverter 230V AC output

- ES100 II 48V 105Ah 5.04kWh TBB Power rack mounted Lithium Battery

- 40A circuit breaker

- 2 x ring terminals

Steca Solarix 1500W 48V pure sine wave power inverter 230V AC output:

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.
