Warranty and RMA
Ten years on the battery, two to five on the electronics, and a process that does not require you to ship a 2,400 kg cabinet back to China to get an answer.
Warranty Terms

|---|---|---|
| LFP battery (APOLLO, ATHENA, SCRA-R) | 10 years | ≥70% of nameplate capacity |

How a Claim Works
- Send the serial number, the installation date and the monitoring export for the affected period
- We respond within 2 business days with a diagnosis or a request for specific measurements
- If replacement is needed, we ship from the regional stock point or from the factory
- Defective units are scrapped locally where permitted — we do not ask you to return heavy equipment
- Credit or replacement is issued once the diagnosis is confirmed
What Is Not Covered
- Damage from reverse polarity, lightning without external SPD, or flooding
- Operation outside the published temperature and humidity range
- Unauthorised firmware modification or BMS bypass
- Capacity loss from charging below 0 °C without a heated pack
- Cosmetic damage after acceptance
Spare Parts
We hold BMS boards, fans, breakers, rectifier modules and communication gateways for every current model. For projects over 500 kWh we recommend a project-specific spares kit quoted at order time — it is cheaper than air-freighting a single board later.
