Brand New 200Ah Sealed Vented Lead Acid Battery

The Technology – Sterling’s high integrity valve regulated lead acid (VRLA) batteries operate as a starved electrolyte system, in which the electrolyte is limited to the amount that either is absorbed in the batteries 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 leads to longer-life battery in a clean and compact container that 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.

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 twice 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 eeffectively 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.
