Product Description         
Feel confident that your family is safe from storms and outages through reliable, energy-conscious technology solutions, and be less reliant on the grid.
Compared with the more common lithium cobalt oxide and lithium manganate batteries currently on the market, lithium iron phosphate batteries have at least the following five advantages: higher safety, longer service life, and no heavy metals and rare metals (raw materials). low cost), supports fast charging, and has a wide operating temperature range.
At present, the lithium-ion batteries used in most mobile power supplies on the market have a cycle life of about 500-800 times, while lithium iron phosphate batteries have a lifespan of at least 2,000 times, and their capacity can still be maintained at 80 %above. Therefore, if the internal storage unit of the mobile power supply is a product of lithium iron phosphate, it has the absolute advantage of normal service life.

Below are the answers to the questions that you may like to ask for


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.
