Multifunctional Usage
Built in battery solar freezer with PMU and MPPT

Method : Built-In Lithium Battery and Integrated PMU (Solar-Only Solution)
Accessory: Solar Panels
Usage: This method uses solar panels with a built-in lithium battery and Power Management Unit (PMU). The solar panels charge the built-in battery directly, eliminating the need for a separate controller or external battery charger. The freezer can also be powered and recharged via an AC/DC adapter, and external batteries can be added as needed for extended power.

1.Multiple Power Supply: With a universal power supply design, it supports power supply of DC 17 – 72V and AC 100 – 240V. It can also be directly connected to solar panels for charging. It is plug-and-play and requires no installation.
2.Powerful Battery: Built-in with a 12.8V – 80Ah (1024wh) lithium iron phosphate battery, paired with a built-in PMU (Power Management Unit) with MPPT.
3.Excellent Insulation: It has an 110mm CFC-free insulating wall. Compared with similar ordinary freezers, it can save 60% of the energy consumption of solar panels and batteries.

4.Wide Temperature Range Refrigeration: When the ambient temperature is 43°C, it can still reach -18°C, and keep the food fresh within 12 hours after power failure.
5.Intelligent Energy Saving: It has automatic voltage detection, is super energy-efficient, suitable for various DC applications, and has low maintenance cost and is easy to clean.
6.Multiple Protections: It has electronic protection functions such as reverse polarity protection and deep discharge protection.
7.Flexible Applications: It can be used as a refrigerator or freezer, is compatible with wind power, solar power and grid power, and is suitable for multiple scenarios such as households, villages, farms and cold chains.

8.Sturdy and Durable: The lid, hinge and cabinet body are extremely strong and sturdy, with a high-temperature resistant design.
9.Convenient Operation: It supports switching between Celsius and Fahrenheit temperature scales, can be intelligently preset for operation, self-checks 9 kinds of faults and gives alarms. It has a built-in cabinet lamp and full numerical control.
10.Adaptable to Climate: It has a forced air-cooled finned condenser, which is suitable for tropical climate.
11.Economical Maintenance: The battery maintenance cost is 15% lower than that of ordinary freezers. It comes with a self-locking DC power cord plug and a built-in backup temperature probe.

Off-grid system planning

Built-in battery solar freezer questions

A solar freezer with a built-in battery combines cooling and stored power in one appliance package. Final operating time, solar-panel size and battery performance depend on the selected model, ambient temperature, set temperature, product load and local sunshine conditions.

Integrated power storage

The battery is housed with the appliance, reducing the number of separate components for projects that prefer an integrated off-grid cooling solution.

Plan for the real application

Share the required capacity, location, stored products and expected daily use so the appropriate freezer and solar configuration can be discussed.

Choose the insulation level

Thicker insulation can help reduce heat gain in demanding environments. Compare built-in-battery options with 110mm insulated solar freezers for your project.

Frequently asked questions

Can a solar freezer with a built-in battery run at night?

Yes, the stored battery power is intended to support cooling when solar input is unavailable. Actual overnight operating time depends on the model, battery condition, ambient temperature, set temperature, door openings and the thermal load inside the freezer.

How long does the built-in battery last?

There is no single runtime for every installation. A quotation should be based on the freezer model, expected daily load, local solar resource and the required autonomy period. Besuncool can discuss the application details before recommending a configuration.

What is the difference between a built-in battery solar freezer and an external battery system?

A built-in battery design keeps the storage component inside the appliance package and can simplify the equipment layout. An external battery system may offer different sizing or service arrangements. The suitable option depends on the project, installation space and power-storage requirements.

What size solar panel is needed for a solar freezer?

Panel sizing should be confirmed for the exact model and installation conditions. It is affected by freezer energy use, local sunshine, ambient temperature, battery capacity and the required recovery time after cloudy weather. Provide the destination and application when requesting guidance.

Which applications suit a built-in battery solar freezer?

These systems can be considered for off-grid homes, small shops, farms, rural projects and mobile or remote cooling applications where an integrated solar-powered freezer package is preferred.
