NOTE - MPPT and Battery Protect need to be in a weatherproof kennel or box. We have a battery box that may be suitable here: Durite Battery Box
DC Must run direct from the battery and battery protect, rather than the MPPT 'LOAD'.
Set battery protect to option '7' disconnect at 11,8V / 23,6V.
MPPT must be connected directly to the battery, NOT via the battery protect. The battery protect is to ensure there is always enough power for the MPPT to continue working in a low battery state and should be set
FEATURES
• Deep cycle AGM technology
• Plus carbon technology
• Lead calcium grids for extended life.
Sealed Construction
Sterling’s unique construction and sealing technique ensures no electrolyte leakage from case or terminals.
Electrolyte Suspension System
All HPC series batteries utilise Sterling’s unique electrolyte suspension system incorporating a microfiber glass mat to retain the maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free electrolyte to escape from the cells.
Control of Gas Generation
The design of HPC series batteries incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use.
Terminals
Sterling’s HPC series batteries are manufactured using a range of terminals which vary in size and type. Please see datasheet in downloads tab.
Valve Regulated Design
The batteries are equipped with a simple, safe low pressure venting system which releases excess gas and automatically reseals should there be a build up of gas within the battery due to severe overcharge. Note. On no account should the battery be charged in a sealed container.
Charging (25C/77F)
Standby use: Float charging voltage 13.5V to 13.8V. (Temperature compensation recommended)
Cyclic use: maximum charging current (see front page). Charging voltage 14.4V - 15V.
Top charge: Product in storage (ambient temperature) required a top charge every 6 months at 25oC (77oF). For higher temperatures, time intervals will be shorter.
Discharge
Stop operation when voltage has reached the minimum permissable voltage; recharge immediately.
Storage
Always store battery in fully charged condition.
Store batteries in a dry and cool location.
Temperature
For standby use, batteries should be kept in an ambient temperature of 25oC.
Caution
• Do not short circuit
• Do not charge in a sealed container • Service life and operational characteristics will be affected by temperature
• AC ripple reduces service life

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:
¹ If using Lithium battery, customer should use “PCsoftware” to set the lithium battery parameters
² Ingress of solid objects:Protected against solid objects over 2.5mm
² Ingress of liquids: Protected against falling drops of water, if the case is disposed up to 15 from vertical
Electronic Protections:
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.
