Will the home have power if the machine is damaged?

If the inverter is damaged, appliances connected to it lose power. If the battery is damaged but the inverter works, AC power can still provide energy. A transfer switch is recommended for full backup.

What is the warranty period for the battery?

The battery comes with an 8-year warranty, and the designed life is over 10 years.

AI-Powered supplier vetting

SummaryChangsha Deligreen Power Co., Ltd. is a China-based trading company established in 2017, with 12 employees and a valid import/export license. It offers battery chargers, EV charging products, cables, and battery-monitoring products, and reports broad export-market coverage. The supplier states annual production of 10,000,000 active battery balancers and order fulfillment within 15 workdays in both peak and off-peak periods. However, it has no supplier-management-system certification, no new products launched in the past year, no ODM, major-brand OEM, or SDK capability, and only minor customization capability. Service governance is weakly documented: complaint handling and corrective/preventive-action procedures have no written procedures or records. It has an overseas warehouse but no overseas showroom, agents or branches, or offline trade-show participation. Customer feedback is self-reported as 99.5% positive, but no customer cases are provided.

CertificationsThe supplier’s certification of management systems is explicitly recorded as NIL. No management-system certification is evidenced in the provided information.

After-Sales capabilityThe supplier claims fast and reliable after-sales service and 99.5% positive customer feedback, and it has an overseas warehouse. However, it reports no written procedures or records for complaint handling or corrective and preventive actions, with no overseas agents or branches, so formal service capability is inadequately controlled.

R&D capabilityThe supplier reports two years of total R&D-engineer experience, but no new products were launched during the past year. It also states no R&D product-information progress, no ODM service, no major-brand OEM capability, and no available SDK, indicating limited documented innovation capability.

Production capacityThe supplier reports 10,000,000 pieces of annual active battery-balancer output, order fulfillment within 15 workdays in both peak and off-peak seasons, and six quality-control staff, while operating with 12 employees overall. These figures support stated production and delivery capacity, although its trading-company classification means manufacturing arrangements are not fully clarified.

Product Q&A

Q:How are the parameters set up for the battery system?

The factory sets up parameters before delivery, and an instruction manual is included to teach you how to set them up yourself if needed.

Q:What does 'PV failure' mean in this system?

It means the solar panel provides low voltage due to cloudy days or nighttime, which is lower than the battery's demand voltage. The battery will then charge from AC power.

Q:How does the system charge when PV priority is selected but PV fails?

In PV priority mode, the system uses solar energy first. If PV fails, it switches to charging from AC power (on-grid) while providing energy to appliances.

Q:What is the difference between PV Priority and Inverter Priority output modes?

PV priority uses solar energy first. Inverter priority means both PV and AC energy pass through the inverter to power appliances, even if there is no PV power.

Q:Does the machine have a CAN communication interface?

Yes, the machine supports CAN communication, along with RS485 and RS232 interfaces as shown in the specifications.
