Solar Choice’s Independent Review of Bosch Solar Inverters and Batteries

 

The BPT-S range of single-phase string inverters from Bosch includes four variants with AC outputs of 3kW, 3.68kW, 4kW, and 4.6kW, which are suited for most home solar PV systems.

Integrated data logging with an online monitoring interface — allowing customers, installers, and manufacturers to remotely monitor performance and troubleshoot issues.

High yields and easy system design are possible because to the wide maximum power point (MPP) range of 170V to 600V, as well as improved MPP tracking processes.

Safety — An innovative service switch checks for defects on both the DC and AC sides of the system, disconnecting the inverter if one is detected.

The PowerCool cooling concept optimizes the inverter’s heat dispersion, resulting in a longer overall lifespan.

Setup is simple with Bosch’s e.

Key — Using touchless radio frequency identification (RFID) technology, the installer may establish the required parameters for Australia with a swipe of a card, ensuring that the settings are correct.

The design is simple and elegant.

BPT-S 5 Hybrid Solar Battery by Bosch

Battery storage capacity ranges from 4.4kWh to 13.2kWh.

The BPT-S 5 Hybrid Battery from Bosch is an award-winning energy storage solution for the home. The refrigerator-sized unit has a storage capacity of up to 13.2kWh, which is enough to make an average-sized household mostly grid-independent. Bosch Power Tec has sold hundreds of the BPT-S 5 Hybrid Batteries around the world, and Australia is an important and developing market for the company.

 

 

The following are some of the key features: Integrated energy management system – A 5kW solar inverter, a battery converter, a battery management system, and a lithium-ion battery bank with a capacity of 4.4 to 13.2kWh, as well as an energy management and control panel with a color touch screen display, make up the Hybrid system.

Allows the user to maximize their savings by avoiding the purchase of expensive grid electricity through programmable, intelligent usage of solar PV, batteries, and the grid. According to four pre-programmed’modes’ for morning, afternoon, evening, and night, the system selects where to acquire and direct electricity most cost-effectively.

 

Maximizing solar PV self-consumption – The BPT-S 5 Hybrid can assist a typical four-person family increase solar self-consumption from 30% to 70%. A high charge performance of 5kW means that in the summer, a household of this size may attain ultimate grid independence.

 

Intelligent system management and display — The Hybrid system includes a touch-screen display that displays current and historical household energy usage and production, as well as system health and maintenance. Bosch’s e.Web and e.UserApp can also be used to monitor the system remotely.

Government Programs for Home Batteries can be found here. Throughout Australia

A home battery plan is currently in effect in South Australia, New South Wales, Victoria, and the Australian Capital Territory.

 

The South Australian Home Battery Scheme provides up to $4,000 per installed battery to qualifying South Australian citizens.

 

The New South Wales Home Battery Scheme provides qualified homes with a $9000 interest-free loan to install a solar battery.

 

The Victorian government offers a maximum discount of $4,174 off the battery sale price to individuals who qualify under the Solar Homes Program. The next round of battery rebates will be available on September 2nd, 2020.

Under the Next Generation Energy Storage program, the Australian Capital Territory government offers a $825 per kilowatt-hour incentive (kW). A typical household with a 5kW system would be eligible for around $4,000 in rebates.
