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.

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.

Extremely hard to get hold of these panels, these are new stock which have been in storage for a project which didn't go ahead.  Brand new, but might have some dusty frames!  Grab them while you can! Very Limited Stocks

These panels do not have shading issues like other panels.  Shade only affects the actual amount shaded, unlike crystalline panel.  Great for boats or campers where partial shading can often happen.

These CIS thin film panels out perform Crystalline panels in lower light levels.  We have done side by side tests in winter and found that with winter sun these panels will give a decent about of additional power over crystalline panels.  In cloudy conditions they both perform the same, with very low output, but then the low powered winter sun does shine the CIS panels out perform the crystalline panels with upto double the power from the same sized array.  Over a yearly yield we would estimate that you may gain around 10% more power generated over the year.  You will require more surface area for these panels, but work out a similar price per watt.

These are framed panels that you can use in off grid or on grid solutions.  In off grid you can only use an MPPT with these panels and the panels must all be run in parallel.

Solar Frontier’s new SF165 module offers the highest conversion efficiency of any mass-produced thin-film module - up to 13.8%.

The modules feature the lightsoaking effect unique to Solar Frontier’s CIS technology, which provides higher output than initially specified. All modules are RoHS compliant and cadmium and lead-free.

All modules also have MCS (Microgeneration Scheme) approval required to register for the Feed-In Tariff.

Fewer production steps and raw materials also mean an industry-leading energy payback time of less than one year.

Solar Frontier Thin Film modules are shipped in cardboard-free packaging and use recyclable corner pieces.

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.
