Does the AGM Ultracell 12V 18Ah battery require special declaration or authorization?

No, this 12V 18Ah AGM battery requires no administrative declaration. Its intermediate capacity and sealed AGM technology make it perfectly suited for residential and commercial solar installations without particular regulatory constraints in France or Belgium.

Does this battery improve my photovoltaic energy autonomy?

Absolutely. This 18Ah AGM battery efficiently stores energy produced by your solar panels to power your 12V equipment for several hours without sunlight. It provides ideal autonomy for lighting, ventilation, alarm systems and photovoltaic monitoring equipment.

Which photovoltaic systems is the AGM Ultracell battery compatible with?

This 12V 18Ah battery is compatible with all 12V solar systems, including PWM and MPPT regulators, 12V inverters, solar pumping systems and monitoring installations. It accepts standard charging voltages (13.5V-13.8V) and supports charging current up to 5.4A.

Can multiple AGM Ultracell 18Ah batteries be installed in parallel?

Yes, these AGM batteries can be connected in parallel to multiply storage capacity. With their low internal resistance (16mΩ) and homogeneous technology, they are perfectly suited for parallel configurations for larger photovoltaic systems.

Is the AGM Ultracell 18Ah battery suitable for off-grid installations?

Perfectly. This AGM battery is ideal for off-grid sites thanks to its sealed, maintenance-free and shock-resistant technology. Its low self-discharge (1-3% per month), 5-year lifespan and 500-1200 cycles make it an excellent choice for cabins, RVs or off-grid installations.

What solar panel power is needed to charge this battery?

For a 12V 18Ah battery, a 50 to 100W solar panel is optimal depending on usage. With a 75W panel, you get a full charge in one sunny day. This combination is perfect for autonomously powering LED lighting, ventilation, pumps or surveillance systems.
