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.

SRNE MA2430N15: Intelligent solar charge controller with CAN communication

The MA series controller adopts industry-leading MPPT maximum power tracking technology to achieve maximum energy from the solar panel. It can quickly and accurately track the solar cell's maximum power point in any environment and obtain solar energy in real time. Maximum solar panel energy can dramatically improve the energy utilization rate of the solar system. Widely used in off-grid solar photovoltaic systems, solar panel, battery and load management is the central control component of an off-grid photovoltaic system. Inside the controller, there are perfect software and hardware fault detection and protection functions, which can minimize installation errors and system failures. component damage.

- Using MPPT technology, MPPT tracking efficiency can reach 99.9%.
- Support for CAN communication function (optional).
- Support for a wide variety of batteries such as sealed, colloidal, open type, lithium and user-customized.
- Support for charging voltage line loss compensation, for more precise control of battery charging voltage (partial models).
- Support for capacitive start-up charging and inductive charging.
- RS485 communication supporting standard Modbus protocol, with adjustable baud rate.
- TTL communication supporting standard Modbus protocol, with fixed baud rate.
- With perfect load and discharge protection mechanisms, such as overvoltage, overcurrent, overload, overtemperature and short-circuit.
