What is the battery capacity and lifespan of the TSOL-MAU8000?

The TSOL-MAU8000 is equipped with a 8000 Wh LiFePO4 battery. It is highly durable, designed to last for up to 6000 life cycles.

Can this unit provide backup power during a grid outage?

Yes. The system features grid-forming capability via its dedicated off-grid port. In the event of a power outage, it delivers a rapid switch time of just 10 ms to keep your essential appliances running without interruption

How does the TSOL-MAU8000 integrate with existing PV systems?

As a Micro AC Coupled Unit, the MAU8000 integrates directly on the AC side of the system. This architecture allows for seamless retrofitting without the need to replace existing string/microinverters or reconfigure the primary DC solar arrays.

How scalable is the system for projects with higher energy demands?

The system is designed with Parallel Output for Single/Three-phase Grids. For scalability, it supports parallel connection of a maximum of 4 units. This provides flexibility for varying residential or light-commercial requirements across both single-phase and three-phase architectures.

What are the physical dimensions and handling requirements for installation?

The unit dimensions are 480 x 750 x 210 mm $(W\times H\times D)$ and it weighs 70 kg. Due to the weight, a two-person team or appropriate lifting equipment is recommended during site positioning. Its IP65 ingress protection allows for versatile indoor or outdoor placement.

How does the system handle grid management and smart tariffs?

The unit is highly compliant with modern smart grid demands. When paired with a compatible meter , it supports strict Zero Export control to prevent unauthorized grid feed-in. It also features Time-of-use Control and is Dynamic Tariff Applicable, enabling you to offer clients advanced energy arbitrage capabilities.
