How the Moixa Smart Battery fits into your life

Smart energy for your home
The Moixa Smart Battery is installed near your consumer unit (fuse box) and measures the energy coming from your solar panels, and being used in your home. Its built-in technology knows when to store your energy and when to provide it.

Storing solar & off-peak energy

When your solar panels generate more energy than your home needs, the Moixa Smart Battery stores it for use later. If you have a special ‘time-of-use’ tariff, then your Moixa Smart Battery can deliver further savings by storing low-cost energy, so you can buy less energy at high-price peak periods. Let our team know if you are on a special tariff so we can ensure your Moixa Smart Battery is best optimised for you.

Battery Safety Instructions

Installing the Moixa Optimised Battery System will require modifications to the distribution board or consumer unit (fuse box) of your property, in order to allow monitoring of the energy characteristics of your home. Carrying out any electrical work in a home or workplace can be dangerous, and only certified electricians may carry out the installation of the Moixa Optimised Battery System, which must be in accordance with the national safety regulations BS7671 or the equivalent applicable regulations in the country of installation.
Please read the following instructions carefully as failure to observe the precautions may result in damage or could invalidate your Installation and Manufacturer’s warranties.

To ensure your product is safely and correctly installed, your installer must follow the guidance laid out in the Installer Manual.

In the event of a fire near the Moixa Smart Battery, perform the following measures:
If the Moixa Smart Battery itself is on fire, do not try to extinguish it yourself. Evacuate the property, call the fire brigade and inform them that you have a Moixa Smart Battery on fire which contains Lithium Ion components. The fire brigade will need to extinguish the fire using specialist equipment. The customer should provide the MSDS https://www.moixa.com/wp-content/uploads/2019/07/ MSDS.pdf. When safe to do so, call Moixa Customer Support at the earliest opportunity.
- If it is safe to do so, turn the isolator switch to OFF, extinguish the fire near the Moixa Smart Battery and contact Customer Support.
- If it is not safe to turn the isolator switch off, switch it off at the consumer unit (fuse box), then extinguish the fire near the unit and contact Customer Support.
If your Moixa Smart Battery becomes damaged, wet or if you notice any unusual noises or smells, disconnect it by turning your isolator switch to OFF and contact Customer Support.
If your Moixa Smart Battery starts to leak and someone is exposed to the liquid, they should seek immediate medical assistance. You must also turn the isolator switch to OFF and contact Customer Support.
For proper ventilation, 100mm of free space is required to the left, right, top and front sides of the
Moixa Smart Battery. Covering it could cause it to overheat or stop working.
Keep children and animals away from the Moixa Smart Battery.
After your Moixa Smart Battery has been installed you must inform Customer Support of any significant electrical work that you are planning, such as any changes to your consumer unit (fuse box), as this may impact your Moixa Smart Battery’s performance.
Do not attempt to tamper with, disconnect, disassemble, repair or move the Moixa Smart Battery. This can only be carried out by a Moixa Accredited Installer, organised by Moixa.
Do not expose the Moixa Smart Battery to an open flame or sources of heat and do not keep flammable objects or liquids nearby.
Do not expose the Moixa Smart Battery to temperatures in excess of 35° C or under 18° C.
Do not pierce the Moixa Smart Battery, place objects on top of it or subject it to strong impacts.

Please note: Once the Moixa Hub and your connected device(s) have been fully installed, Customer Support must be notified of any significant electrical work that you are planning to conduct in your home. This includes any changes to your consumer unit, as this may impact the performance of the Moixa Hub and connected device(s).

Firewalls

Your Moixa Smart Battery must be connected to the internet for you to receive full functionality, and you must not interfere with this connection. Below are the minimum recommendations that are required for correct operation of the Moixa Hub:

TCP Port: 8833 MQTTS -> AWS (any IP)
TCP Port: 22 -> SSH Jano (any IP)
TCP Port:443 -> HTTPS (any)
UDP Port:53 -> any IP

The above are subject to change without notice, and we recommend allowing the following in order to avoid disruption:

Inbound rules: any IP – disabled, any port – disabled
Outbound rules: any IP – allowed, any port – allowed

Maintenance and Troubleshooting

If you change your electricity provider or tariff, notify Moixa, or your local customer support, by email (see contact section 5.0). It is important Moixa has your up to date tariff information to fully optimise your system.

Unless there is an emergency, or situation as described in the Battery Safety Instructions, you must not attempt to shut down your Moixa Smart Battery unless instructed to do so by Customer Support. If a nonemergency fault does occur with your Moixa Smart Battery, please contact Customer Support and they will be happy to assist.

Shutting down

Turn the isolator switch that connects the Moixa Smart Battery to the mains in the house from the ON to the OFF position. If your Moixa Smart Battery was installed with a red and yellow isolator switch like the one shown on the right, this will involve turning the red switch anti-clockwise from ON to OFF. Once the switch is off, you should expect the screen to go black.

Restarting

Before restarting, please leave the isolator switch in the OFF position for 30 seconds. Then turn the isolator switch back to ON. Once the Moixa Smart Battery has restarted the screen should turn on.

Product Performance and Maintenance

Your Moixa Smart Battery should not require your attention or onsite maintenance to function correctly. However, if you are concerned that your Moixa Smart Battery is not performing as expected, we recommend checking your Moixa Dashboard or app. Here you should be able to see the amount of energy stored in the battery increasing and decreasing throughout the day with your solar generation and household consumption. If you
are unsure whether your Moixa Smart Battery is performing as expected, please contact Customer Support.

The Moixa team will also look out for any Moixa Smart Batteries that are not working as expected, and if any issues are detected we will try and resolve these remotely. If the issue cannot be resolved remotely, the Customer Support team will reach out to you and arrange for one of our Moixa Accredited Installers to visit your premises and resolve the issue.

To further guarantee uninterrupted operation and optimal performance of the Moixa Smart Battery, we recommend that:

Your household electrical system is inspected periodically to ensure it is compliant with all required standards. The scheduled inspection due date for the Moixa Smart Battery installation should be mentioned by the installer on the EIC form.
You check for accumulated dust and other contaminants on the surface of the Moixa Smart Battery and, if required, use a soft and lint-free cloth to remove these. Please avoid using solvents or water for cleaning.

Battery health: In order to prolong the lifetime of your Moixa Smart Battery and comply with the manufacturer’s requirements, the system must be charged to full at least once per month. Usually this need is met through normal operation. However if your PV system doesn’t generate enough power and/or you don’t charge it overnight from E7/smart tariff, your Moixa Smart Battery has programmed to launch the “self-maintenance mode”, during which it will set itself to charge up to full. That might result in charging from the grid.

Moixa Dashboard and app

Overview

The Moixa Dashboard and app allows you to view your home’s energy data through your personal online account. Your energy graphs and information will help you understand how much solar energy you generate, how much energy you use in your home and how your Moixa Smart Battery is supporting your energy needs.

Account Setup

During your Moixa Smart Battery installation, an account will be created for you to access the Moixa Dashboard and app. This account will be assigned to the email address that you provide to your Moixa Accredited Installer on the day. You should receive an email from hello@moixa. com which will explain the next steps to get signed up. If you have not heard from Moixa after 3 working days, check your junk email account for an email from [email protected] or reach out to [email protected].
