Photovoltaic System Accessories
Photovoltaic system components always require various accessories. Solar batteries are the core. Your system will also require photovoltaic panels, solar controllers, inverters, and possibly monitors, busbars, circuit breakers, etc.
Affordable Energy Solutions
Some European countries adopt peak and valley electricity prices, which makes electricity prices very expensive in some countries during certain periods of time. WattCycle's solar batteries provide you with efficient and economical solutions to manage your energy needs.
On-Grid
A solar on-grid system, also known as a grid-tied solar system, is linked to both the solar panels and the main grid. This means you can draw power from your panels or the grid, and you can also automatically send excess solar power to the grid.
Off-Grid
An off-grid solar system is a solar panel system that has no connection to the utility grid at all. This means that all of your system's power comes from the panels, so you don't need to rely on an external power source. You can meet your energy needs entirely through solar power and stored batteries.
Hybird
A hybrid solar system is a system that uses the combination and integration of solar power with a backup power source (usually a generator or the main grid) and battery storage to generate electricity.
Reliable and Long-lasting Solar Power
WattCycle's solar batteries are equipped with automotive grade-A+ LiFePO4 cells and advanced BMS, ensuring top-tier energy performance and long-lasting power output. These high-quality batteries are designed for long-term reliability. Your best home storage power choice!

Real Stories About WattCycle Solar Batteries
Know More About Solar Battery Information
What is a solar battery?
A solar battery stores excess electricity generated by solar panels. When solar panels are unable to generate enough electricity, such as at night, on cloudy days, and during power outages, you can use the stored energy to power your home.
Which battery is the best for solar?
Lithium iron phosphate battery!
Pros:
- Higher Energy Density: Compared to traditional lead-acid batteries, LiFePO4 batteries are smaller in size, lighter in weight, and have 2X more energy because LiFePO4 batteries have a higher energy density.
- No Maintenance Hassle: LiFePO4 batteries are green and environmentally friendly and do not require frequent cleaning and maintenance.
- High Depth of Discharge (DoD): LiFePO4 batteries support 5000 - 15.000 cycles, 100% DoD, providing more than 10 years lifespan.
- Rapid and Safe Charging: Most LiFePO4 batteries can be fully charged in four hours or less, depending on the capacity of the solar panel used for charging. In addition, lithium-ion batteries have built-in overcharge protection to ensure that overcharging does not damage the battery.
Are lithium solar batteries safe?
Lithium solar batteries are a safer type of battery than traditional lead-acid batteries, although they have the same safety risks as other types of batteries, including overheating and fire.
