2x Your SigenStor DCEV charging speed with a software upgrade

If you purchased a 12.5 kW Sigenergy SigenStor EVDC Charger from Perth Solar Warehouse, you have great news: your charger can now be upgraded to a 25 kW charging capacity through an over-the-air software update. This means no new hardware, no electrician visit, and no disruption.

This manufacturer-supported upgrade allows eligible customers to unlock double the charging power with a paid software license. As a result, you'll enjoy faster EV charging and greater long-term value from the system you already own.

Key insights

• Double your charging power instantly: Upgrade your existing 12.5 kW Sigenergy EVDC Charger to 25 kW via a simple over-the-air software unlock, with no hardware changes or site visit required.
• Gain the performance of a 25 kW DC charger for a fraction of the cost of replacing your unit, delivering faster charging, improved future EV compatibility, and better use of your solar and battery system.

Unlocking the 25 kW charging capability offers several real-world benefits, including significantly faster charging times that are particularly advantageous for busy households or those with multiple electric vehicles. This upgrade also reduces wait times when topping up your vehicle, allowing for a more efficient driving experience. Furthermore, it enhances the utilisation of solar, battery, and grid power within your Sigenergy system, making it a more sustainable option.

Significantly, this enhancement raises the maximum charging limit of your EVDC charger from 12.5 kW to 25 kW. However, it is essential to note that the actual charging power available at any given time will still depend on factors such as the energy generated by your solar PV system, battery capacity, inverter rating, and grid input. This is normal system behaviour and does not indicate a fault.

Performance expectations (very important)

After upgrading to 25 kW, your Sigenergy EVDC charger will be capable of delivering up to 25 kW of DC charging power, provided that sufficient energy is available in your system. This device unlocking means faster charging when solar production is strong, battery capacity is available, or grid support is enabled.

If energy availability is limited, such as during low solar output or when household energy demands are high, the charger will automatically adjust and operate at a lower power level. This behaviour is normal and ensures that your system operates safely and efficiently, while also taking advantage of higher charging speeds whenever conditions permit.

No Hardware Changes – 100% Over-the-Air

One of the most significant advantages of this upgrade is convenience. The 25 kW capability is unlocked via a software license activated remotely using the mySigen app. That means:

• No charger replacement
• No rewiring or physical modifications
• No technician site visit required

Once the license is purchased and activated, the charger is digitally upgraded and ready to deliver higher power when system conditions permit. For older EVDC units, Sigenergy provides an updated nameplate at no charge to ensure regulatory compliance.

Cost

The fee to unlock the 25 kW upgrade is $1,100 AUD. This represents an exceptional value compared to purchasing a brand-new 25 kW DC charger and covering the installation costs. By choosing the upgrade, you effectively double your charger's capacity at a fraction of the cost of replacement, all while retaining the trusted Sigenergy hardware that is already integrated into your energy system.

How to Get Started

If you’re interested in upgrading and unsure how to move forward with confidence, Perth Solar Warehouse is here to help ensure that PSW customers have a suitable system and guide them through the process. Alternatively, if you're ready and willing, follow these three steps:

1. Open the mySigen app and visit the Mall section.
2. Purchase the SigenStor EVDC 25kW Fast Charging License with a credit card.
3. Receive your License Key, copy it, and activate it on your specific EVDC device.

Note: For older EVDC models, a free replacement nameplate will be provided and must be installed to meet local regulatory requirements.
