Solar power,
day and night

Moonwatt’s system uses advanced sodium‑ion NFPP chemistry, chosen for its intrinsic material abundance and superior safety profile:

• Excellent cycle life: predictable degradation and long-term reliability.
• High thermal stability: reduced risk of thermal runaway.
• No lithium, no scarce metals: scalable global supply.
• Low‑ and high‑temperature resilience: consistent performance across climates.

NFPP provides the electrochemical backbone that enables a more robust, safer, and future‑proof storage system.

Moonwatt developed an ultra‑efficient passive cooling architecture with no moving parts. This results in:

• Silent operation
• Near‑zero battery enclosure O&M due to the absence of HVAC and fans
• High IP protection against dust, water, and air ingress
• Stable performance during prolonged heatwaves or cold spells

By eliminating complex thermal machinery, reliability increases, costs decrease, and long‑term field performance improves dramatically.

Following the same philosophy that transformed the solar inverter market, Moonwatt’s system embraces a distributed, modular architecture:

• Deploy anywhere, including directly under solar panels
• Lightweight design, transportable with a standard forklift
• No foundations required
• Easy scaling from kW to multi‑GW
• Ideal for new solar builds and retrofits

This string‑level approach reduces land use, simplifies installation, and unlocks a more flexible project design.

Moonwatt integrates solar and storage at the low voltage level, either through DC coupling via a hybrid inverter or AC coupling at the LV busbar, creating an architecture that:

• Eliminates the need for additional MV transformers
• Reduces electrical balance-of-plant costs
• Minimises conversion losses across the charge/discharge path
• Enables charging from clipped solar power
• Increases overall plant round-trip efficiency 

The result is a more efficient and cost-effective hybrid solar-storage system.
