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.

Three-phase battery inverter

The perfect solution for integrating energy storage into your PV system, whether on- or off-grid.

The ME 5K...20KTL-3PH is a high-voltage, three-phase battery inverter designed for integrating storage into existing PV systems, or systems with a high demand for battery charging. In the event of a grid failure, it can provide up to 20 kW of unbalanced three-phase emergency power supply (EPS) in just 10 ms, thanks to its integrated EPS port.

Equipped with two MPPTs and two independent battery ports (available on models 10K to 20KTL), this UPS allows different battery capacity configurations. In particular, it is compatible with SOFARSOLAR's HT (high voltage) battery series (GTX 3000-H and BTS battery storage system).

Up to 10 inverters can be connected in parallel on the EPS and AC ports, making it an ideal choice for both on-grid and off-grid microgrid installations.

The integrated energy management system offers a variety of user-friendly modes, optimizing the user experience, including an automatic self-use mode. Users can also define different time slots and/or dates, as well as rules for each day of the week.

All modes are easily configured via the large LCD display. What's more, a Wi-Fi key is supplied with the UPS, enabling easy connection to the SOFAR View monitoring portal.
