The Steca PF 240 is the most efficient DC energy-saving refrigerator ever to be developed. It can be used as either a refrigerator or a freezer. It can be run from solar direct or a battery.

The Steca PF 240 are fully programmable. The inside temperature and each of the other configuration values can be set by the user. They are therefore perfectly suited for all DC applications including even the refrigeration of medicines in hospitals. Thanks to the latest A+++ energy efficiency class, together with optimal electronic control and an RPM control of the compressor, it is possible to ensure that the energy is used extremely efficiently. This leads to significant cost reductions.

This product stands out for its user-friendliness, thanks to a large digital display with setting options, the highest standards of quality and reliability and a long service life. The refrigerator or freezer is easy to clean as it has a sealing plug on the bottom for draining water. This maintenance-free appliance can work with an input voltage of either 12 V or 24 V.

Can be run of only an 80W solar system, see our packages for a suitable system to run this fridge.

Brand New 110Ah Sealed Vented Lead Acid Battery (Terminal options at foot of this text)

The Technology – Sterling’s high integrity valve regulated lead acid (VRLA) batteries operate as a starved electrolyte system.  The electrolyte is limited to the amount that either is absorbed in the battery plates or wets the fibres in the separator.  The resulting system allows gases produced during overcharge to diffuse from one plate to the other, and to be recombined back into the electrolyte.

This recombination creates a closed system, thus reducing the release of gases into the atmosphere under normal discharge conditions.

Since the electrolyte is recycled, there is no need to add water to the batteries.  This reduced maintenance and leads to a longer life battery in a clean and compact container.  They can be installed when flooded batteries are impractical.

Features & Benefits

• Tank formed construction allows for individual plates to be inspected prior to battery assembly, eliminating manufacturing defects. Plates are fully formed guaranteeing 100% capacity on delivery.

• Sterling’s unique construction and sealing techniques ensures no electrolyte leakage from case or terminals, allowing batteries to be positioned on their side.

• Excellent recovery from deep discharge.

• Low self discharge – approx 3% per month.

• Not restricted for air transport – complies with IATA ICAO special provision A67.

• Impact resistant ABS case and cover.

• Industry standard footprints for easy field replacement.

• Maintenance free.

• 98% recyclable

Charging: (25°C / 77°F)
Standby use: Float charging voltage 13.50V to 13.80V.

Top up charge: Product in storage (ambient temperature) requires a top up charge every 6 months.  Apply constant voltage at 2.40 volts per cell, initial charging current should be set at less than 0.1 CA for 15 to 20 hours

Life expectancy

• Standby use: 3 - 5 years.
• Cycle use (approx):
• 100% depth of discharge 200 cycles
• 50% depth of discharge 450 cycles
• 30% depth of discharge 1000 cycles

Comes with bolts.

New XTRA series - 3rd Generation MPPT

For 12V Solar System: 390W solar panel (150V for max input voltage)
For 24V Solar System: 780W solar panel (150V for max input voltage)

No Fan for silent operation, great for vans, boats or any live in spaces

With built in LCD advanced display and programming screen (XDS2)

New XTRA series has Lithium battery support (set via PC cable only)

​The XTRA tracer models have a current limiting function, you can connect 1.5 times the rated power to the controller ​so if your on a budget you can use a smaller controller with more panels so that you get more power in winter or low light but don't risk overloading the controller in the summer.  The output will be limited to the max listed above.

New EPEver (Tracer) series is EPsolar’s third generation of MPPT controller.

XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off grid photovoltaic systems, with display unit.

In order to maximise the energy harvest from PV arrays and simultaneously minimise the power loss within a wide range of operating conditions, XTRA series apply an advanced smart algorithm which results in up to 30% higher efficient charging, compared to a conventional pulse width modulation (PWM) charge controller. Xtra series controller have limit protection function on charging current &charging power, as well as auto derating power operation at high temperature; the above protection ensure the stability of system even at exceeded rated PV power and over temperature conditions.

Protection class IP32 and isolated RS485 communication port further improve the controller’s reliability under different application requirements. XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital control circuit, which effectively prolongs the lifespan of battery and significantly improve the system performance. It also has extensive electronic protection for overcharge, over discharge, PV&battery reverse polarity and etc. to ensure the sustainability and durability of the o-grid solar system.

Features:

• Advanced MPPT technology & ultra-fast tracking speed is up to 99.5% guaranteed
• Maximum DC/DC transfer efficiency is as high as 98%, full load transfer efficiency is up to 97.4%
• Wide MPP operating voltage range
• Low temperature protection and self activate function for lithium battery charging
• Limit charging power & current over rated range
