Frequently Asked Questions

Cycle life is specific to the battery model and test conditions. Check the datasheet for the rated cycles, depth of discharge, temperature and charge or discharge rate. A cycle rating should not be treated as a guaranteed number of years in every installation.

An ideal estimate is battery energy in kWh divided by load power in kW. For example, 60kWh divided by a constant 30kW load gives 2 hours before accounting for reserve capacity and losses. Actual runtime depends on usable capacity, efficiency, operating limits and the load profile.

Selected battery models support parallel connection. Use matching models and specifications, preferably from the same production batch, and follow the approved wiring and communication instructions. Confirm the permitted configuration with our team before expanding a battery bank.

We do not recommend mixing batteries with different ages, brands or specifications in one parallel bank. Differences in voltage, internal resistance and control settings can cause uneven current sharing or communication issues. Ask our technical team to assess an existing system before adding batteries.

The maximum parallel count depends on the exact battery model, BMS and system configuration. Check the model datasheet and approved connection diagram before ordering. Tell us your required capacity so we can recommend a supported configuration.

Use series wiring only when the exact model manual permits it. Do not assume that a configuration approved for a 12V battery also applies to a 48V or 51.2V battery. Confirm the required voltage and approved battery arrangement with our technical team before installation.

Send us the inverter brand, exact model and battery model before purchase. We will check the voltage range, charging limits, communication protocol and cable requirements. Some combinations may need compatibility testing. Matching voltage alone does not confirm that a battery and inverter will work together.

Possible causes include an unsupported protocol, the wrong communication cable, incorrect wiring or mismatched settings. Send the exact product models, fault message and clear connection photos to our team. Use the approved wiring diagram and settings for that product combination.

Only inverter models designed for parallel operation can be connected in this way. The permitted number, firmware, communication equipment and wiring depend on the model. Use matching units and request the model-specific parallel connection guide before planning the system.

An off-grid inverter may accept utility power for charging or backup without being designed to export electricity to the grid. Grid export requires an appropriate grid-interactive system and configuration. Tell us whether your project needs grid charging, backup or export so we can select the right solution.

Certain system configurations support off-grid operation and generator integration. Generator input, automatic start and transfer functions depend on the selected inverter, controls and wiring. Share the generator details and project requirements so our team can confirm the supported operating modes.

Grid-tied inverters operate with the utility grid. Off-grid inverters support standalone power systems. Hybrid models combine solar, battery and grid functions, with capabilities that vary by model. If backup during an outage is required, confirm the dedicated backup output and system design before ordering.

The product range includes fan-cooled systems and liquid-cooled energy storage cabinets. The cooling method depends on the exact system, so check the specification for the model being quoted. Follow the installation manual for ventilation space and operating conditions.

We can provide available user manuals, wiring diagrams and installation videos, together with remote technical support. Training or on-site guidance may be arranged depending on the project and agreed service scope. Confirm these arrangements before ordering.

Anern is a manufacturer with in-house R&D. OEM and ODM options can include branding, packaging and agreed product configurations. Send your technical requirements, target market and order quantity so our team can confirm the customization scope for the project.

You can request a sample by sending the model number and required quantity. Our sales team will confirm availability, sample pricing, production time and shipping arrangements before you place the order.

Bulk and project pricing depends on the product, quantity, configuration and delivery requirements. Send your model list and expected order volume for a quotation. Our team will assess the available pricing for the specific order.

Lead time depends on the model, quantity, stock availability and customization requirements. Our team will confirm the production schedule and shipping estimate for your order. Production time and international transit time should be checked separately.

Our engineering team provides remote technical support. Send the product model, serial number, fault description and clear photos or videos to help us assess the issue. Confirm any local service arrangements with our team for your destination and order.

The applicable warranty period and coverage depend on the inverter model and the agreed sales terms. Check the warranty policy or quotation for your exact product before ordering. Contact our team if you need help confirming the terms.

Warranty duration and coverage are specified in the warranty policy or quotation for the battery model. Manufacturing defects may be covered subject to those terms. Damage from misuse, incorrect installation or operation outside specified conditions may be excluded. Confirm the applicable policy before ordering.

Contact our support team with the model, serial number, purchase details and fault evidence. After assessment, we will confirm the appropriate remedy under the applicable warranty terms. Spare parts, replacement arrangements and shipping responsibilities will be agreed for the individual case.

Available documents depend on the exact product model. Visit Certificates & Reports for published UN38.3 test summaries and reports. If your project requires another standard or destination-market document, send us the model and requirement so our team can verify availability.

Shipping requirements depend on the battery configuration, quantity, route and transport mode. Ask for the available model-specific test documents before shipment and confirm the shipment requirements with the appointed logistics provider. Our team can help coordinate the relevant product information.
