If you want to monitor additional circuits at a site that already has Hybird hardware installed, you can purchase additional breakers through the Hybird webshop and have your installer add them to the existing system. This article covers the full process.
Step 1: Plan the expansion
Before ordering, determine:
How many additional circuits you want to monitor.
What breaker type is needed for each circuit (RCBO, MCB, or RCD) and the correct rating (amps, poles, curve type).
Whether your existing panel has physical space on the DIN rail for additional breakers.
Whether your existing RS485 bus can accommodate more devices (recommended maximum of 80 breakers per controller; hard protocol limit is 247).
Step 2: Order through the Hybird webshop
Go to hybird-energy.myshopify.com and add the required breakers to your cart.
Important - use the Special Instructions field at checkout: If you are adding breakers to an existing installation, you must note this in the "Special instructions" field during checkout. State:
That this is an addition to an existing installation (not a new build).
The site name and controller name/ID where the breakers will be added.
The Modbus IDs currently in use on that controller's RS485 bus, so Hybird can pre-configure the new breakers with non-conflicting addresses.
This ensures the new breakers arrive with Modbus IDs that do not conflict with your existing devices. If you do not provide this information, you will need to re-address the breakers manually on site.
Step 3: Check Modbus IDs before installation
Every breaker on the RS485 bus must have a unique Modbus ID. Before installing the new breakers, confirm which IDs are already in use on the existing controller. You can check this in Hybird OS by viewing the controller's device list, which shows all currently connected breakers and their Modbus IDs.
If the new breakers were pre-configured by Hybird (because you provided the existing IDs in your order), they should be ready to connect without conflict. If you need to change a Modbus ID on site, refer to the breaker commissioning documentation or contact Hybird support.
Step 4: Installation
A certified Hybird installer visits the site to:
Mount the new breakers on the DIN rail.
Wire the new breakers into their respective circuits.
Tighten terminals to the recommended torque (2 Nm for breakers up to 25A, 3.5 Nm for 25-80A).
Connect the new breakers to the existing RS485 daisy chain using the supplied pre-cut wire (rated 110°C / 600V).
Run a breaker scan in Hybird OS to verify all new breakers are discovered and communicating.
Label and name each new breaker in Hybird OS to match the circuit it protects.
If the total number of breakers on the controller exceeds the recommended maximum of 80, consider adding a second controller. Contact Hybird support to discuss multi-controller site setup.
Step 5: Verify and commission
After installation, check in Hybird OS that:
All new breakers appear in the controller's device list with correct Modbus IDs.
Each new breaker is reporting measurements (voltage, current, power, temperature, leakage).
Remote switching works for each new breaker (test on/off via Hybird OS).
If you have Hybird Optimisation, the new circuits can be classified as flexible or fixed and included in the optimisation schedule.
Impact on your service contract
Adding circuits may affect your monthly Hybird Service fee (499 DKK/month excl. VAT is the base rate). Contact [email protected] to confirm whether your fee changes before ordering.
Your Hybird Connect is priced at 49 DKK ex. VAT per month per installation (588 DKK per year, invoiced annually). VAT) covers the controller and is not affected by adding breakers.
No downtime to existing monitoring
Adding breakers to an existing RS485 bus does not require taking the existing system offline. The controller continues monitoring all currently connected breakers while the new ones are being physically installed. Once the new breakers are wired into the daisy chain and a bus scan is run, they begin reporting alongside the existing devices.
