Notes: 

• When charging and discharging the battery, ensure that the battery voltage, current and temperature monitoring and protection conditions.
• Please keep the battery away from the heat source, fire source and other heating and corrosive environments with strong acid and alkali.
• Do not short-connect the battery or install the incorrect polarity at any time.
• Do not mix the batteries of different models or different manufacturers.
• Do not use external force to make the battery fall, impact or puncture. Do not disassemble the battery or change the external structure.
• When the battery is not used for a long time, please keep the battery charge at 30%~50%SOC state, and avoid being in strong sunlight Shooting or high temperature and high humidity environment.

Can I charge the battery from the mains?

Short answer is yes but it will require a hybrid inverter. This would mean you could charge the battery at a cheap night rate from the grid as well as charging the battery from the solar PV.

Can I have an Uninterrupted supply (UPS) if there is a powercut?

Yes but would need to be wired to a dedicated circuit within the house, for example the upstairs sockets and downstairs lighting, this would then provide you with emergency power in the event of you losing the mains.

What’s the best location for batteries?

They work best in a room that doesn’t get too hot – Ideally they would go in a garage but they can go in a loft or any other room but the warmer they get the less efficient they become. The operating temperature ranges from -10 to 50 degrees but will see efficiency drops below 0 and above 40 degrees

Are Batteries safe?

Batteries are no more unsafe than any other electrical installation, as with anything there are risks but these are very small and should be a great consideration.

Can I add more batteries at a later date?

Yes, this battery can be in 4S and 4 Parallels, maximum reach 51.2V 400Ah for the model of 12V100Ah. 

How long do they last?

This is actually determined by the number of cycles the battery goes through, this means a full charge and discharge. On average a battery will last around 10 years and all batteries have at least a 5 year warranty and most can be extended to 10-years.

What’s the difference between Capacity and useable capacity?

Most batteries will have a capacity and a useable capacity – this can be confusing but in basic terms batteries should never been fully discharged and as such the useable capacity takes this into account.
