Demand Response Mode (DRM) in the MultiPlus-II is an operational mode that enables the system to participate in demand-response grid events.

This mode is configured when the AS4777.2 (Australia/New Zealand) grid code is selected in VEConfigure.

DRM allows the grid operator to send signals to the inverter to curtail the amount of power fed back to the grid during certain conditions.

Technically, this is achieved by setting up a resistance value between 5kOhm and 16kOhm on the AUX1 port, which acts as a trigger.

If the grid needs to reduce intake due to high production or low demand, it can signal this through the AUX1 port, causing the MultiPlus-II to disconnect from the grid if the resistance changes, thus contributing to grid stability.

This feature ensures that the inverter responds appropriately to grid demands and operates within the parameters set by grid regulations.

In the ‘on’ position, the system is fully active, allowing the inverter to convert the DC supply to AC power.

When AC voltage is present at the ‘AC in’ terminal and is within acceptable parameters, this voltage is directly passed through to the ‘AC out’ terminal, bypassing the inverter, which is then placed in standby mode.

Concurrently, the system’s charger initiates the charging cycle for the connected batteries, signified by the illuminated ‘bulk’, ‘absorption’, or ‘float’ LEDs, each indicating the current charging phase based on the battery’s condition.

When set to ‘charger only’, the system disengages the inverter circuitry while maintaining the charger function, assuming AC input is available. This mode ensures that voltage from the ‘AC in’ terminal is supplied to the ‘AC out’ terminal without inverter intervention, thus preventing battery depletion from inverter activation during fluctuations or absence of AC input.

This mode is crucial for maintaining battery charge by avoiding unnecessary inverter operation, especially during stable grid supply conditions or specific maintenance scenarios.

Here’s a breakdown on protecting the AC input of your 3kVA MultiPlus-II, that you need to consider:

• Fuse or Magnetic Circuit Breaker: The 3 kVA MultiPlus-II model requires an AC input to be safeguarded by a fuse or a magnetic circuit breaker. This protection should be rated at 32A or lower. It’s vital to ensure that this protective device matches the maximum input current specification to prevent potential damage due to overcurrent conditions.

• Selecting the Proper Rating: A 32A rating is selected based on the power output of the inverter. Since a 3kVA inverter can potentially draw significant current, especially when supplying power to large loads or charging batteries, this rating provides a buffer to accommodate peak currents without tripping.

• Cable Cross-Section Sizing: The cable that connects the AC source to your MultiPlus-II must be of an appropriate gauge to handle the maximum current without overheating. For a 32A circuit breaker, you will typically need cable conductors that can handle the amperage without excessive voltage drop, which is particularly important over longer runs.

• Downsizing for Lower Rated Supplies: If the AC input supply you’re connecting to is rated for less than 32A, you will need to downsize your protection to match the supply. For example, if your input supply is only rated at 20A, then a 20A fuse or breaker should be used.

• System Coordination: The chosen protection rating must also coordinate with other system protections, such as those on the AC output side, to ensure that any faults are isolated and do not affect the entire system.

Protection Device Rating:

• The AC input of your 5 kVA MultiPlus-II should be protected by either a fuse or a magnetic circuit breaker.

• This protective device should be rated at 50A or lower. The choice of a 50A rating takes into account the maximum power that the inverter/charger can draw from the AC source.

Cable Cross-Section Sizing:

• The cables used for the AC input connection should have a cross-sectional area that’s adequate to handle the current corresponding to a 50A protection device.

• This ensures that the cables can carry the current without excessive heating or voltage drop, which is essential for safety and efficiency.

Matching with AC Supply Rating:

• If your input AC supply is rated lower than 50A, it’s important to match the rating of your protection device to the supply rating.

• For example, if your AC supply is rated at 30A, then a 30A fuse or breaker should be used. This is to ensure that the protection device trips appropriately in case of an overload, thereby preventing potential hazards.

Considerations for Inrush Currents:

• While the normal operating current might be lower than the breaker rating, the 50A rating provides a buffer for the inrush currents that can occur when the inverter/charger starts up or when large loads are switched on.
