27DC115-115Ah -12V

Wet lead acid battery - generally not suitable for mobile applications. Should not be located in living areas.

Since 1926 Crown Battery has responded to the 'power' challenges and individual needs of industry leaders with the best available products and services in the field of heavy-duty commercial deep cycle batteries.

A company wide dedication to quality control and continual improvement has earned Crown Battery the highest quality and service rating in the industry.  "We put more into our deep cycle batteries so you can get more out of them...

More performance, more productivity with less maintenance. Nobody builds them like Crown, because no one else invests in the heaviest, thickest plates in the industry.  Our plates are over 10% thicker than our competitors.

Combine that with our proprietary PROeye and our low maintenance container - features that make battery maintenance predictable and efficient - and you've got a battery that's going to last longer and perform like no other."

• More productivity with less maintenance.
• Thicker and heavier plates, combined with heavy strap and intercell connections is the 'Crown' signature.
• Manufactured to exact standards to deliver the longest run time and battery life.
• More performance.

Crown out-performs the competition in head to head tests over and over again.

"It must be a matter of perspective. But we aren’t prone to exaggeration, the way some of our competitors are.

If you claim to have batteries that out-perform all others, an independent laboratory should confirm the findings.  That’s the way we do it at Crown.  Since 1926, that’s all we’ve done.  And to us, it really isn’t a matter of claiming to be first in the industrial marketplace; but being the best. Some manufacturers are comfortable making exaggerated claims.

We’re comfortable making battery history… one customer at a time."

The Industry Heavyweight

"The heaviest, thickest plates in the industry.  Thicker plates, heavier lead connections, and the most active lead material per ampere hour of rated capacity.  And heavy means more lead, more active material.  Which means more power.  Longer life.  Who would you put your money on?  A lightweight battery? Or the heavyweight of the world.  Crown."

High Efficiency Poly PERC Half-Cell Module (CS3K-285-290-295-305P)   Dimensions: 1675 × 992 × 40mm

CANADIAN SOLAR INC.is committed to providing high quality solar products, solar system solutions and services to customers around the world. As a leading PV project developer and manufacturer of solar modules with about 30 GW deployed around the world since 2001, Canadian Solar Inc. is one of the most bankable solar companies worldwide.

With proprietary poly wafer and cell technologies Canadian Solar have developed an extraordinary module range. HiKu are the first poly PERC modules with up to 335W output from an almost standard 60 cell module frame size. Combining the best technology and design, it also reduces LCOE and installation costs.

With Canadian Solar’s industry leading poly-PERC cell technology and the innovative LIC (Low Internal Current) module technology, we are now able to offer our global customers high power poly percium modules up to 300 W.

• The KuPower poly modules with a dimension of 1675 ˣ 992 mm, close to our 60 cell modules, have the following unique features:
• Higher power classes for equivalent module sizes
• High module efficiency up to 18.11 %
• LOW hot spot temperature risk
• LOW temperature coefficient (Pmax): -0.39 % / °C
• LOW NMOT (Nominal Module Operating Temperature): 43 ± 2 °C

Power Range: up to 305 W

Cell: 120 x dual-cell Percium Poly, 156 x 78 mm

Dimensions: 1675 × 992 × 35 mm

New XTRA series - 3rd Generation MPPT

For 12V Solar System: 260W solar panel (100V for max input voltage)
For 24V Solar System: 520W solar panel (100V 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.

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
• Real-time energy statistics function
• Multiple load work modes
• Comprehensive electronic protection
• Compatible with lead acid and lithium-ion¹ batteries
• Over temperature protection and power degrading in higher temperature
• Optional LCD display units (XDB1/XDS1/XDS2) and accessories
• High quality and low failure rate components of ST or IR to ensure service life
• Isolated RS485 communication port with 5V/200mA protected output, with standard Modbus protocol Monitor and set the parameters via APP or PC software
• Dustproof and waterproof design with IP32² protection class
• CE certification(LVD IEC62109,EMC EN3/1-6-61000)

The BatteryProtect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.

12/24V auto ranging
The BatteryProtect automatically detects system voltage

Programming made easy
The BatteryProtect can be set to engage / disengage at several different voltages. The seven segment display will indicate which setting has been chosen.

A special setting for Li-ion batteries
In this mode the Battery Protect can be controlled by the VE.Bus BMS.
Note: the Battery Protect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual.

Ultra low current consumption
This is important in case of Li-ion batteries, especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.

Over voltage protection
To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16V respectively 32V.

Ignition proof
No relays but MOSFET switches, and therefore no sparks.

Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.

Delayed load disconnect and delayed reconnect
The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected.
The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.
