Service & Warranty Commitment
One line: Warranty, lead time, documentation and technical support are written into the contract for each order — not left as verbal reassurance.
Warranty
| Item | Standard warranty | Notes |
|---|---|---|
| Inverters (HE200 / HE300 / HE310) | 2 years | From date of shipment |
| LiFePO4 battery systems (H3B / H4B) | 5 years | From date of shipment |
| All-in-one ESS (H3 / H4 / L2) | Quoted per model | Confirm at quotation |
Warranty covers manufacturing defects and component failure under normal installation and operating conditions. It does not cover damage from incorrect battery voltage configuration, water ingress beyond the model's IP rating, unauthorised disassembly, or installation that does not follow the supplied manual. Installing or wiring errors that damage the unit are not covered — this is why we ship the wiring and configuration guide with every batch.
Lead time and shipping
| Order type | Typical lead time |
|---|---|
| Single model, stock item | 7–15 days from order confirmation |
| Mixed container / multiple models | 20–35 days |
| Parallel (FP) systems, battery packs | Made to order — quoted individually |
Lead times are stated as typical, not guaranteed. Battery and all-in-one ESS models are currently quoted without UN38.3 test reports, which affects air and sea transport booking — we will tell you at quotation whether a model can ship to your destination and by what route, rather than assuming.
Documentation with every order
Every shipment is accompanied by:
- Model-specific specification sheet
- Installation and wiring guide (connection sequence, cable sizes, breaker ratings)
- Parameter-setting guide (battery type, charge current, SBU thresholds)
- Fault-code and alarm reference
- Certification files applicable to the shipped model range
Documentation is supplied in English by default. Additional languages can be arranged for volume orders.
Technical support
Pre-sale, we will match a model to your load schedule rather than simply quoting the largest unit. Send the load list, backup hours required and battery chemistry, and we will come back with a sizing recommendation and the reasoning behind it.
After-sale, first-line troubleshooting runs off the fault-code reference. Where an issue needs an engineering-level answer — board-level faults, firmware, BMS protocol mismatches — we escalate it through the supply chain and relay the answer back.
Spare parts and repair
Common replaceable parts (fans, control boards, display boards) can be supplied with orders or as spares. Board-level repair requires the unit to be returned or a local service partner; we will state which route applies before you commit to a repair plan.
What we commit to commercially
- No unverifiable claims. Certification is always quoted with its model range. Where a file is not held for a model or market, we say so.
- Honest lead times. If a model is made to order, we say it is made to order.
- One point of contact. Commercial, documentation and technical follow-up run through the same contact, so nothing is lost between departments.
- Your brand, stated up front. For private-label orders, every change — mark, label, carton, manual — is confirmed in writing before production. See OEM / ODM.
