Replacement of lead-acid batteries with lithium batteries: Pylontech US2000C 48V 2.4kWh
Batteries are a fundamental part of any self-consumption photovoltaic installation. Thanks to the energy accumulated in them, we can increase our independence from the grid for more hours a day. With batteries we can have the electricity we have been generating even late at night, when the panels have stopped producing energy, without having to depend on the electricity grid and its prices. Traditionally, lead-acid batteries were installed to accumulate the photovoltaic energy but, little by little and as technology has advanced, these batteries have been replaced by lithium batteriesas the Pylontech US2000C 48VThe new, much safer, more compact and more durable.
Our customer had an outdated, bulky and inefficient bank of lead-acid batteries. These batteries were taking up a lot of space in the basement and, after a few years of use, were at the end of their useful life. So he started looking for options and found the best alternative in the Pylontech US2000C 48V 2.4kWh batteries.
While replacing a lead-acid battery bank with a lithium battery may seem like a simple task, it is actually a process that requires very specific technical knowledge and skills. It is often thought to be as simple as connecting the batteries to the inverter and that's it, but it is essential to follow the proper steps in order for everything to work safely. It is necessary to design the system correctly, connect all the components and, above all, set the inverter to the correct voltages for the batteries to avoid possible damage to the equipment. A poorly configured inverter-charger can end up breaking the batteries connected to it, rendering them unusable shortly after installation. This is a common mistake that is very expensive.

Lead-acid vs. lithium batteries: Pylontech US2000C 48V 2.4kWh
The first difference between lead-acid and lithium batteries is obvious: size. Lead-acid batteries of the same capacity as lithium batteries take up more than three times as much space and weigh ten times as much.
What are the advantages of lithium batteries?
The advantages of lithium are many: higher capacity, higher energy density, lower weight and volume, longer lifetime, short charging times, maintenance-free.
Although the price of these batteries is still higher than lead-acid batteries, so are the range of features they offer.
