What is the Tesla collection?
The Tesla collection brings together the Powerwall ecosystem for residential storage: high-density lithium battery, Backup Gateway for switching and metering, sensors (CT clamps, RS485/Neurio cables), and the Wall Connector charger for electric vehicles. It is an AC-coupled solution that integrates with solar installations from different brands, providing backup, time-based management, and app monitoring.
Advantages and limitations
- AC integration: compatible with most existing grid-tied inverters without changing the PV array.
- Automatic backup and dynamic load control via Gateway and bidirectional metering.
- Single app for battery, home energy, and EV charger, with automations based on hourly pricing.
- Scalable architecture (multiple Powerwall units with coupling and dedicated accessories).
- Limitations: requires Gateway for backup/islanding; installation by qualified personnel and compliance with local regulations.
Applications
- Homes with self-consumption seeking to store surplus and maintain critical loads during outages.
- Households with an electric vehicle charger wishing to charge with solar or during off-peak hours.
- Modernization projects for existing installations (retrofit) without replacing the PV inverter.
How to choose your Tesla system
- Usable energy: size the total capacity (number of Powerwall units) according to daily kWh and desired backup level.
- Backup: if you want power during outages, include the Backup Gateway and define the critical loads subpanel.
- Metering: add CTs and sensor wiring for zero export, balancing, and reliable automations.
- Integration: check installation space, AC protections, and coordination with your electrical panel.

Best practices
- Define critical loads and backup power before choosing the number of batteries.
- Check selectivity and protections in AC, as well as cable cross-section and room ventilation.
- Correctly configure the CTs for bidirectional metering and charge/discharge strategies.
- If there is an existing PV system, coordinate zero export with the inverter meter or the Gateway.
