Home backup, a battery for an existing system, or power for individual devices. Start with what you need.
A battery for your system
Check your inverter’s battery voltage, communication and charging requirements, then consider capacity.

- kWPower
- Consider the appliances running at the same time, and account for their startup demand separately.
- kWhEnergy
- How much energy is stored. Actual runtime also depends on the load, usable energy and operating conditions.
Two configurations. The same 6 kW inverter.
More battery modules do not increase inverter output.

Four things to share before selection.
Appliances that need to keep running
Start with whether you need backup for essential appliances or a wider set of home loads. List the appliances, quantities and backup time. Add nameplate power and startup requirements if known; otherwise describe what you need to power.
Local electrical supply
Share the country or region and, if known, voltage, frequency and phase. Language or a country name alone does not establish the electrical requirements.
Existing equipment and photographs
For existing inverters, batteries or PV modules, share the model numbers or available nameplate photographs. Matching voltage, connectors or communication interface names alone does not establish compatibility.
Installation space and conditions
Describe the location, available space and approximate temperatures. Charging, discharging and system operating limits need separate checks; site images can help the discussion.
You do not need every detail to begin. Describe your needs in the form, paste an image or attach images / PDFs. Leave uncertain details blank and we can clarify them together.
Before choosing a model, review inverter output, battery energy and installation limits together. Before connecting to home wiring, an installer with the qualifications required locally should confirm connections, protection and backup circuits. Existing nameplate or site photographs can help; there is no need to open equipment or electrical panels for a photo.

From questions to clarity
A few more things to clarify.
All-in-one or separate inverter and battery?
Start with the equipment you already have. An all-in-one system integrates the inverter and battery; a separate system requires both devices and their connections to be checked together. For expansion, confirm the existing voltage, communication and permitted expansion method. Both formats need to suit the actual load and installation conditions, beyond appearance or energy capacity.
Compare storage formatsWhy does inverter selection go beyond kW?
Rated output is one requirement. Check AC and battery voltage, PV input range and charging limits as well. Battery voltage can change with the power configuration; review Pro and single-unit models separately. For multiple inverters, confirm parallel operation and its conditions for the exact model, rather than borrowing another model’s capabilities.
View inverter configurationsWhere can a system be installed in cold weather?
Charging and discharging have different limits. For the vertical system shown here, the battery charge range is 0–50 °C and discharge range is −15–50 °C. The installation must still meet the selected model’s temperature, enclosure, ventilation and connection requirements.
See this system’s installation conditionsCan I replace the battery on my existing inverter?
The same voltage or connector alone does not confirm a match. Charging and discharging settings, communication and protection also need checking. Tell us your equipment model and we can help clarify the pairing requirements.
Which documents should I look at first?
Start with the exact model’s specifications, actual connections and pairing requirements. For certification and service documents, check the covered models, applicant and scope. We can go through these for the product you are considering.
When should shipping and service be confirmed?
During the quotation stage. Agree on the destination, delivery responsibilities and service terms, so you can compare the same scope of supply rather than the equipment price alone.
