STORAGE AND BATTERIES

Key Components of the Photovoltaic Storage System

01

BATTERIES:

Batteries are the main component of the storage system. They can be of different types, with the most common being lithium-ion, lead-acid, and flow batteries. Batteries store energy in the form of direct current (DC)
02

INVERTER:

The inverter converts the direct current (DC) stored in the batteries into alternating current (AC), which is the form of electricity used by most household appliances and equipment.
03

CHARGE CONTROLLER:

This device regulates the flow of energy between the solar panels, the batteries, and the electrical grid, ensuring that the batteries are charged safely and efficiently without overcharging or excessive discharging.
04

Energy Management System (EMS):

An EMS manages and optimizes the use of stored energy, prioritizing consumption based on demand and the availability of solar energy, and can integrate other energy sources and loads.

Can a photovoltaic solar system be installed initially and then expanded with batteries?
Yes, it is perfectly possible to install a photovoltaic solar system initially and then expand it by adding batteries. This is a common and viable strategy that offers flexibility and scalability to your energy system. The initial installation of solar panels can provide a renewable energy source and reduce your dependence on the conventional electrical grid. Subsequently, adding batteries allows you to store excess energy generated during the day for use during the night or on cloudy days, providing greater autonomy and stability to the system. It is important to properly plan the system's capacity, the compatibility of the inverter and other components, as well as consider the physical space and wiring requirements needed for the integration of the batteries.

Can I increase the capacity of my photovoltaic solar system with batteries?
An efficient way to increase the storage capacity of your system is by using high-capacity batteries. These batteries are designed to store a larger amount of energy and, in many applications, can directly replace standard batteries.

Do batteries work if there is no electrical grid?

Yes, batteries can operate without an active electrical grid. When a photovoltaic solar system is connected to storage batteries, these can store the energy generated by the solar panels during the day for later use, even when the electrical grid is disconnected or unavailable.

In situations where the electrical grid experiences power outages, the batteries act as a backup power source, supplying electricity to devices and equipment connected in your home or business. This backup power is invaluable during blackouts or emergency situations, providing continuity in electrical supply and ensuring the operation of critical devices such as lights, security systems, refrigerators, and medical equipment, among others.

How much capacity do the batteries have and what is their average discharge rate?
The capacity of a battery is measured in ampere-hours (Ah) and represents the amount of current it can supply over a specific period. For example, a battery with a capacity of 100 Ah, if discharged continuously at a current of 5 amps, will be completely depleted in 20 hours.

What type of warranties do batteries offer and what is their lifespan?
The warranty and lifespan are approximately 13 years.

Can a battery be installed with Watt Energia if we did not do the initial installation?
Yes, adding a battery to an existing photovoltaic solar system is an excellent way to improve energy efficiency and increase autonomy.
