Disadvantage of lead acid batteries
When lead acid batteries fail in small off grid solar systems it can be catastrophic. No power for water pumps, lights or refrigeration. Lead acid batteries can die suddenly, particularly in winter when the colder temperatures cause the chemical process to slow down.
Lead acid batteries need to be fully charged all the time or they can die quickly when lead crystals build up on the internal plates. If they are left partially charged or don’t get full very often this can cause rapid deterioration. Lithium batteries do not suffer from this problem. They can be left fully discharged for weeks without affecting the battery capacity or life.
Old 24 Volt systems often need to be totally upgraded to work with most, new 48V Lithium batteries and this is very expensive, having to replace everything just because the batteries have failed.
New Pylontech 24V Lithium battery solution
Not anymore! Pylontech have a new 24V Lithium battery solution that can work with most existing inverters and solar panels. Each battery holds 2.5 kWh of usable power and upgrading is simple and easy.
Most Lithium batteries require up to date charge controllers that allow 2 way communication to the Battery Management System (BMS) to ensure the batteries can control the charging. The Pylontech UP2500 batteries can use a simple charge voltage setting and can work with a variety of legacy charge controllers.
A lot of otherwise good equipment ends up on the scrapheap because of incompatibility with new technologies. This waste is now avoidable with these Pylontech batteries.
Pylontech have designed all their new batteries to be able to work with all their previous models, ensuring that you can add more storage capacity at any time without causing headaches when one battery won’t work with another. A lot of other brands bring out new products all the time and stop making the old models, so you can’t add more storage without throwing out all your perfectly good old batteries first.
The Pylontech UP2500 batteries have a five year battery life warranty when working with voltage set older charge controllers and 7 years when connected via CAN communications to a modern device.
Do you have an older 24V off grid system?
