FAQs asked by different countries:
FAQ: SP Series for UK Homes & The Smart Export Guarantee (SEG)
Q: Is this inverter compliant with UK G98/G99 regulations?
A: Yes, the inverter is designed to meet UK grid connection standards (G98/G99). Your installer will ensure it is registered correctly with your Distribution Network Operator (DNO).
Q: Can I benefit from the Smart Export Guarantee (SEG) with this inverter?
A: Absolutely. When configured for grid-tied operation, it allows you to export excess solar energy to the grid, enabling you to get paid through an SEG tariff from your energy supplier.
Q: How reliable is it given the UK's damp weather?
A: With an ingress protection rating of NEMA 3R (equivalent to IP54), it is well-protected against rain and moisture, making it suitable for garage or outdoor wall mounting.
Q: The specs mention a high DC input voltage. Why is this beneficial?
A: A higher DC voltage (up to 600V) allows for longer strings of panels, reducing the amount of cabling and combiner boxes needed, which can lower installation costs.
Q: Can it power my immersion heater directly to heat water?
A: Yes. You can divert excess solar power to an immersion heater or other loads through the backup port or via smart load management, maximizing your self-consumption.
Q: What battery technologies are supported?

Q: Does it have built-in surge protection?
A: Yes, it includes built-in Type II surge arresters on both DC and AC sides, offering excellent protection against lightning and grid voltage spikes.
Q: Is the display easy to understand?
A: The system offers multiple user interfaces: a clear LED/LCD display on the unit itself and a more intuitive, comprehensive view via the wireless APP.
Q: What is the typical lifespan of this inverter?
A: With high-quality components, a robust cooling design, and a wide operating temperature range, it is built for long-term reliability, backed by an extendable 10-year warranty.
Q: Why should a UK homeowner consider this system?
A: It's a future-proof investment that tackles rising energy prices head-on. Generate your own power, earn money by exporting, and gain peace of mind with backup power during outages.
