Service that Safeguards Your Power

"We understand that a home battery isn’t just equipment; it’s continuity, safety, and peace of mind for your family.

That’s why we treat service with the same rigor as engineering. Only when a reliable system is backed by attentive, professional support do you get what truly matters: safety, protection, and lasting confidence."

Teams with International Background

We speak your language.

Our team has studied and worked across Europe, Singapore and the United States etc.

Beyond fluency, we understand the expectations behind the words—so you get clear communication, culturally aware service, and solutions that fit real customer needs.

Worry-Free Return

If it’s not right, we’ll make it right.

A simple, transparent RMA process with clear steps and quick resolutions—repair, replacement, or refund as applicable. No friction, no runaround—just outcomes.

Fast Maintenance Parts Delivery

Local stock, rapid turnaround.

We pre-position maintenance parts for each model in regional warehouses. Most replacements arrive in about one week, minimizing downtime and service visits.

Technical Support

Real engineers on call.

We run initial diagnostics within 24 hours. If escalation is required, a specialist conducts an expert review within 72 hours.

In exceptional cases, we coordinate on-site maintenance with certified partners to get you back up fast.

5-10 Years Warranty

Confidence that lasts.

Every system is backed by a 5-10 years warranty covering manufacturing defects, supported by professional diagnostics, parts access, and replacement options to keep your power reliable.

Logistics Transparency

Always know where your order is.

End-to-end tracking from factory to final delivery, with milestone notifications, ETAs, and documents in a single portal—so you’re never guessing where your shipment stands.

WeVolt Battery Capacity Self-Test Contest

If your battery capacity doesn’t meet the rated spec, we refund you 100%.

To strengthen customer trust and transparency, WeVolt offers a Capacity Self-Test Guarantee.
You can test your battery’s capacity (Ah) at home (or via a third-party). If the verified result, under the conditions below, is lower than the rated capacity for your model (as shown on the nameplate/spec sheet), WeVolt will provide a full refund.

How it works (3 steps)

Step 1

Perform a Capacity (Ah) Test

Recommended measurement (best accuracy):

DC electronic load (constant current) or a DC load setup
A meter that can count Ah (coulomb counter / shunt meter / test log)

Note: AC kWh only is usually not enough to confirm Ah. If you only have AC data, we may ask for DC-side Ah data or a retest.

Step 2

Submit Your Test Results

Send the required evidence so we can verify the test was done correctly.

Required:

Order number / proof of purchase (you may mask sensitive info)
Battery model + clear photo of the serial number (SN)
Screenshots/photos showing:
- Before test: SOC, voltage, temperature
- Fully charged: SOC, voltage, temperature
- End of discharge: total discharged Ah, voltage, temperature, SOC
A short video (or continuous recording) showing:
- SN/label
- Discharge current setting
- End-of-discharge screen with total Ah

Optional (helps faster verification):

Electronic load logs / curves
Coulomb counter data export
Third-party test report

Step 3

Verification & Refund

Once we receive complete materials, we verify and confirm the result.

If verified capacity is below the rated capacity → 100% refund
If evidence or conditions are incomplete → we will request missing items or a retest

Requirements

Test Conditions

To ensure fairness and repeatability, your test must follow:

Ambient temperature: 0–35°C (recommended 20–30°C)
Discharge rate: 0.2C – 0.5C
- C-rate formula: Discharge current (A) = Rated Capacity (Ah) × C
Rest time: After full charge, rest ≥ 2 hours before discharge
Discharge end condition:
- Stop when the system reaches BMS low-voltage cutoff or the manual’s specified cutoff
- Do not stop early
Ah measurement required: Must provide discharged Ah from a coulomb counter/shunt meter/load log
Safety: High current is involved. Use correct cable size, tight terminals, protection (breaker/fuse), ventilation, and safe operation.

Pass/Fail rule

We compare your verified discharged capacity (Ah) to the rated capacity of your model (nameplate/spec sheet).

Pass: Measured capacity ≥ rated capacity
Fail: Measured capacity < rated capacity (under the required conditions) → full refund

If results are near the threshold or evidence is unclear, we may request one retest to eliminate measurement error.
