Wall Mounted Home Batteries: Is Your Home Ready for the Installation?

While wall mounted home batteries can help make a storage installation neat and orderly, the wall isn’t necessarily a good installation location. There must be plenty of support for the enclosure, the area around the enclosure must be usable, and the electrical setup should be similar to that found on the property.

The best place to begin for homeowners and residential installers would be the room, not the battery brochure. Evaluate the site, determine the equipment to be provided and relate it back to the energy needs in the house. The installation should be accessible and usable for years after the initial photo.

Do not begin with the Room, Not an Empty Rectangle!

Observe the room usage during the day for the proposed room. A utility area can include things like doorways, washing machines, storage shelves, etc., that are not visible in the product shot. Look at the battery in conjunction with these activities.

Draw the enclosure and the clearances and space required for installation and subsequent removal. Add any extra inverter, isolation and cable containment. The installation area is greater than the outline area of the battery.

There are several formats of VoltaLink’s residential energy storage products. Where the approved arrangement is appropriate to the building, wall mounting should be considered, but an alternative format may be more appropriate where the wall, access route or available service space is not appropriate.

Use Structural Support as a Model Specific Decision

Wall mounted means the equipment is designed for that type of mounting, but does not mean that all walls can support it. Before accepting the location, be sure to get the exact unit weight, mounting drawing, bracket details and manufacturer’s instructions.

According to VoltaLink’s 51.2V 300Ah wall battery page, the weight of the system is 175kg and the dimensions are 640 × 400 × 1280mm. Those numbers make structural evaluation and arrangements important components of the project. Specify if the provided configuration is wall supported, floor supported or a combination of both.

Get structural input as required and have installation professional evaluate the substrate and structure. Never select fixings from a random and general internet example. Also check the methods by which the unit will be taken to the room and the positioning of the unit without harming the building or equipment.

Check the product package to be sure of what it contains.

There are instances of the same product being sold under various names, with different supply packages. Battery packs require power conversion equipment that is compatible with the battery pack; an integrated system can have inverter functions. Prove the quotation’s range rather than to assume functionality based on the cabinet form.

The published parameter table for VoltaLink’s Wall Mount Lithium Battery System is for a 51.2V battery with a capacity of 314Ah and a rated energy of 16.07kWh. Ask for the final configuration sheet to determine the inverter, communication cables, protective devices and installation accessories included.

Separate out battery specifications from system output specifications. If an inverter is provided, verify the AC voltage, continuous output and operating modes of the inverter. If it’s not, check the exact combination of compatible software. A full equipment definition will not allow space planning around a battery, and will fail to consider the other equipment that is required.

Match the Location with the Environmental Limits

Make sure the specified enclosure rating and operational temperature of the selected model matches the actual room. Take into account humidity, potential water contact, temperature fluctuations in different seasons and heat sources near the area. Even a location indoors may be inappropriate if it is out of range of the product.

The Wall Mount Lithium Battery System parameter table states the use indoors (IP20). That helps with planning for suitable indoor environment, not presuming the suitability of exposure outdoors. Determine the appropriate location (garage, utility room, etc.) before getting the proper installation instructions.

Ensure necessary ventilation and service spaces are maintained. Try not to arrange shelves or home storage spaces so that there is no longer enough room to reach them, over time. The installer must determine placement specifications for the particular property, and not for a totally different model.

Relate Capacity to “How the home uses electricity”.

If a site is identified as possible, ask “why does the household need storage?”. Using the excess solar energy from the day in the evening is not the same as storing energy for when the system fails. The operating conditions and capacities may vary.

Look at consumption over time – don’t just look at a monthly bill. Make comparisons between solar surplus and demand loads during the day and evening and loads for backup. When proposing a configuration, ask the designer to provide for usable capacity, loss, reserve setting and output limits.

VoltaLink offers a solar product, a wall mounted battery, as a product reference. Even then, there is a need for more investigation related to the configuration chosen and the electrical system of the property. The wall-mounted enclosure alone does not make a solar system compatible with existing equipment, or ensure that it can provide a source for electricity in the event of a blackout.

Allow for Cable, Controls and Subsequent Service.

A neat installation will enable you to understand and maintain the equipment. Explain cable on entry, accessibility of cable protection and how a technician is able to get to the connections without breaking down unrelated equipment.

Normal operation should be taken into account, too. The user should be able to see indicators and follow the shutdown or alarm instructions without having to move items in storage. The design of location should not cause the system to be hard to identify or inspect.

If future expansion is important, request a plan for expansion prior to reserving adjacent wall space. Support, wiring, protection and system settings may need to be modified for additional units. If there is only empty space, it does not constitute a feasibility of expansion. Document the proposed arrangement to ensure that future changes will not affect the original installation.

Accept the Installed Arrangement, Not Just the Appearance

Before the handover ensure that the work carried out conforms with the agreed layout and the manufacturer’s instructions. Have the installer describe how it is to be mounted, controls, isolation points and access areas.

The functions that are included in the project should be shown in the commissioning. Analyse charging/discharging characteristics for a solar storage installation. If backup is provided, verify with the installer that he or she can show you the outage procedure that has been approved and what circuits are covered.

Keep the records of installation, model information, manuals and support contact information. Capture a picture of the layout for future reference: cable routing and accessible controls. Review the plan if there are changes to the use of the room or other equipment is added.

Conclusion

It is best to plan a site in conjunction with product selection when using wall mounted home batteries. Look at structural support, equipment scope, environmental suitability and service access before the appearance. Next, compare the storage space and the system’s capabilities with your household requirements. The outcome should be a recorded installation which meets the requirements of the building and which is simple to operate and maintain.

FAQs

Q1. Wall mounted home batteries can be attached to any wall?

No. The actual unit weight, support system and wall construction needs to be determined. Install as per the chosen model’s instructions.

Q2. Does wall mounting mean there are no grounds for space requirements?

No, access for installing and services and floor supporting issues must still be taken into account. Make a detailed plan, not just for the outline of the enclosure.

Q3. Is it possible to install an IP20 home battery in an outside location?

IP20 is not to be considered an outdoor weatherproof rating. Verify an appropriate site following manufacturer’s instructions.

Q4. Does each wall battery come with an inverter?

No. Supply package is dependent on the product and configuration. Check the quotation and final equipment specification.

Q5. Can the other battery be connected next to it at a later time?

However, only with the manufacturer’s approval of the expansion scheme. Ensure that all structural, electrical and compatibility requirements are verified prior to adding equipment.
