Frequently asked questions

Photovoltaic energy is stored in a LiFePO₄ battery and then used for electric cooking beneath a glass-ceramic surface. Cooking does not require a grid connection at the time of use.

Cooking uses previously stored energy and remains possible while sufficient battery energy is available. Solar charging depends on sunlight conditions.

The P0 RevB reference is an 8S LiFePO₄ battery rated at 25.6 V nominal and 80 Ah, or 2.048 kWh nominal. Integration and protection systems remain subject to prototype testing.

Runtime depends on power, heating cycles, losses and protection thresholds. Final figures will follow instrumented tests; no runtime is guaranteed here.

The reservation amount is €360, with a full refund on request until the final order is confirmed. The €360 is fully credited towards the product price; no additional product-price balance is charged. Any delivery charges must be disclosed and agreed separately.

No. Payments are not enabled on prep.touawen.com and no balance is automatically charged.

Until the final order is confirmed, you may cancel and request a full refund by emailing contact@touawen.com with your name, email address and reservation reference. TOUAWEN refunds the full amount without fees to the original payment method, without undue delay and within 14 days of receiving the request. If TOUAWEN cancels the reservation or abandons the project, the amount is refunded in full. This commercial guarantee is additional to, and does not restrict, applicable statutory rights.

Timing depends on prototype validation, testing, sourcing and pilot production. A confirmed date and delivery charges must be communicated before a final order.

Development and conformity preparation are ongoing. A patent is not a safety, conformity or performance certification for the finished product.

Mobile Money payments are not enabled on this test website. Never send TOUAWEN a PIN, password or verification code.
