Robert Bosch GmbH is a global, highly diversified manufacturer whose name is synonymous with quality and reliability. The company’s power technology division – Bosch Power Tec – currently offers a number of solar-related products for Australia’s small-scale solar market. This article focuses on the string inverter line and energy storage solution that Bosch currently available in Australia.
Bosch BPT-S inverter series
Single-phase inverters for residential solar applications
Bosch’s BPT-S line of single-phase string inverters consists of four models for solar PV systems sized at 3kW, 3.68kW, 4kW and 4.6kW (AC output) – ideal for most residential solar PV systems.
Key features include:
- Integrated data logging with online monitoring portal – So that customer, installer and manufacturer alike can monitor performance and troubleshoot problems from afar.
- Flexibility in design and performance – Wide maximum power point (MPP) range of 170V to 600V, combined with improved MPP tracking procedures allow for high yields and easier system design.
- Safety – Innovative service switch automatically checks for errors on both the DC and AC side of the system, disconnecting the inverter in the event of an error message.
- PowerCool cooling concept – Optimises heat distribution of the inverter, allowing for a longer overall lifespan.
- Easy setup with Bosch’s e.Key – Touchless radio frequency identification (RFID) technology allows the installer to set the relevant parameters for Australia with the swipe of a card, ruling out any fault in the settings.
- Sleek design.

4.4kWh – 13.2kWh of battery storage capacity
Bosch’s BPT-S 5 Hybrid is an award-winning energy storage solution designed for the residential market. The refrigerator-sized unit can be equipped with up to 13.2kWh of storage capacity – enough to allow an average-sized household to become mostly grid-independent. Globally, Bosch has sold several hundreds of the BPT-S 5 Hybrid and Australia is a key and growing market for Bosch Power Tec.
Key features include:
- Integrated energy management system – The Hybrid system consists of a 5kW inverter, a battery converter, a battery management system and a lithium-ion battery bank which can be sized between 4.4 and 13.2kWh of capacity, plus an energy management and control panel with a colour touch screen display.
- Programmable, intelligent use of solar PV, batteries and the grid – Allows the user to maximise their savings by avoiding the purchase of expensive grid electricity. The system decides where to source and direct electricity most cost-effectively according to four pre-programmed ‘modes’ for morning, afternoon, evening and night.
- Maximising self-consumption of solar PV – The BPT-S 5 Hybrid can help to increase solar self-consumption for a typical household of four from 30% up to 70%. A high charge performance of 5kW means that a household of this size could even achieve total grid independence in the summer.
- Intelligent system management and display – The Hybrid system comes with a touch-screen display that shows current and historic household energy consumption and production, while also ensuring the ongoing health and maintenance of the system. The system may also be monitored online via Bosch’s e.Web and e.UserApp.
