AC coupling for battery backup with grid tied system

What I''ve done with my SMA system is connect AC coupled PV (Sunny Boy) directly to output of battery inverter (Sunny Island), and use a "load-shed" relay to disconnect loads (house) based on a control signal for low battery SoC. This sheds all load at 70% DoD, leaving 10% to keep AC running waiting for Sunny Boys to wake up.

6 Frequently Asked Questions about “Coupling relay battery”

What is a safe coupling relay?

Safe coupling relays are often used in process technology systems; they electrically isolate and amplify the power of electrical signals for functional safety. Phoenix Contact has developed SIL-certified coupling relays to meet the demands of process technology applications. Why do I need an SIL-certified coupling relay?

What are TÜV-certified SIL coupling relays?

Our TÜV-certified SIL coupling relays for safe switch-on and switch-off enable the electrical isolation of signals up to SIL 3. System downtimes can be reduced to a minimum by diagnostic functions, such as integrated proof test and line load monitoring.

What is a SIL 3 coupling relay?

The SIL 3 coupling relays with ATEX, G3 coating, and temperature range up to 70°C are suitable for special applications in the process industry. Safe coupling relay with force-guided contacts, 2 changeover contacts, 1-channel, fixed screw terminal block, width: 17.5 mm

What is a battery relay?

Battery relays typically contain multiple contacts, which are conductive parts that connect or disconnect electrical circuits. The most common configurations include: Usually Open (NO): This contact remains open when the relay is de-energized and closes when activated.

Are the safe coupling relays SIL-certified?

The safe coupling relays are also SIL-certified. SIL, or safety integrity level, is a method for assessing a system's reliability. Levels SIL 1, SIL 2, and SIL 3 must always be viewed in relation to the hazard. If you choose our SIL-certified coupling relay, you will not need to conduct an assessment.

How do I choose a battery relay?

Selecting the appropriate battery relay involves considering several factors: Voltage Rating: Ensure the relay can handle your system's voltage (e.g., 12V for most automotive applications). Current Rating: Choose a relay that can handle the maximum current your application will draw.
