Brand New 85Ah Sealed Vented Lead Acid Battery
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 leads to a longer life battery in a clean and compact container that can be installed when flooded batteries are impractical.
85Ah (20 hour rate)
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.
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.

The full bridge plus toroidal transformer topology has proven its reliability over many years. The inverters are short circuit proof and protected against overheating, whether due to overload or high ambient temperature. High start-up power Needed to start loads such as power converters for LED lamps, halogen lamps or electric tools. ECO mode When in ECO mode, the inverter will switch to standby when the load decreases below a preset value (min load: 15W). Once in standby the inverter will switch on for a short period (adjustable, default: every 2,5 seconds). If the load exceeds a preset level, the inverter will remain on.
A remote on/off switch can be connected to a two pole connector, or between battery plus and the left hand contact of the two pole connector

New XTRA series - 3rd Generation MPPT - Budget Model
For 12V Solar System: 260W solar panel (60V for max input voltage)
For 24V Solar System: 520W solar panel (60V for max input voltage) *Solar Panels must be 36cell (2 in series) or 72 Cell (1 in series) for use on a 24 Volt battery system*
No Fan for silent operation, great for vans, boats or any live in spaces
Budget Model with no display. Can connect MT50 for remote display.
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 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.
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%
