"The size of your solar battery will depend on your energy needs and the level of independence you desire. To find out what size you need, add up your daily energy consumption in watts per hour (Wh) and multiply it by the number of days the solar battery should last without recharging. Pay attention to the rate of discharge (which can be as high as 90% for lithium batteries). Formula: Battery capacity (Ah) = energy consumption (Wh) / battery voltage (V). "

"The lifetime of solar batteries depends on the technology used: The EcoFlow solar lithium batteries use LFP technology and manage between 3000 and 4000 charging cycles without any loss of their capacity. After that, it will only be reduced to 80%. The lifetime of a solar battery depends on the charging cycles, the depth of discharge and the temperature conditions."

Depending on their capacity, solar batteries can cost between 800 and 1200 euros.

"Yes, because they allow you to store solar energy for later use, increasing your independence from the electric grid. They are particularly advantageous in areas with an unstable electricity supply or in off-grid systems. In addition, you can also use your solar batteries during road trips and outdoor activities. The versatility of these solutions is one of their greatest strengths."

"First, connect the solar battery to the solar charge controller. Then connect the solar panels to the solar charge controller. Finally, connect the inverter."

"Not directly. It can be done in two ways: By connecting a charge controller to it with a boost converter that increases the voltage, or by using two 12V solar panels connected in series to increase the voltage to 24V."

"The solar panel must exceed the battery's nominal voltage (12V). Ideally, we would need a 18V or higher solar panel to compensate for the power losses."

"Yes, as long as the solar charger supports lithium technology and can provide the right charging features (e.g. constant current/constant voltage mode). Many modern MPPT or PWM charge controllers support lithium batteries."

"Yes, if installed properly. EcoFlow X-Guard technology makes their solar batteries waterproof, fireproof and fall-proof. Furthermore, they are ultra-quiet with a background noise level of 30dB, which will not affect your sleep or that of your loved ones."
