Enerdrive ePOWER DC2DC+ Battery Charger 40A:
The Enerdrive ePOWER DC2DC+ Battery Charger is a fully automatic multistage,
multi input battery charger with the ability to charge from either an
alternator linked to a battery; or via solar power with the in built Maximum
Power Point Tracking (MPPT) Solar Controller. With two inputs available, the
main/house battery will be charged from either the engine while underway, or
via the solar panels when stationary. The process to choose either engine or
solar is fully automatic and both functions are controlled from within the
unit itself without the need for external relays. During normal operation the
ePOWER DC2DC+ Battery Charger will do a full charge cycle to float stage on
the house battery bank with ability to choose either GEL, AGM, Flooded, Custom
Programmable or Lithium. Once float stage is reached the charger transitions
to a power supply mode to support any on-board DC loads.
Multistage Charging Process:
The ePOWER DC2DC+ Battery Charger is a fully automatic, set and forget
charger. It is designed to quickly and accurately recharge your deep cycle
batteries utilising charger algorithms that help to maximise the life of your
specialised deep cycle batteries. The ePOWER DC2DC+ Battery Charger features
multistage smart charging technology that enables the charger to be connected
to your battery bank permanently. With the input of multiple sources, you can
be assured of charging your batteries whenever underway; or when the sun is
shining on your solar array. As dictated by battery manufacturer’s
recommendations, deep cycle batteries require a multistage charge sequence for
perfect, fast and accurate charging. The Enerdrive ePOWER DC2DC+ smart charger
delivers three primary charge stages.
Stage 1 – Bulk or Boost charge; The battery is charged at full rated output
current of the charger until the battery reaches its final charging voltage,
known as its absorption voltage. In this step, around 80% of the battery is
recovered as fast as possible.
Stage 2 – Absorption Charge; With the charger voltage held steady, the
remaining 20% is replaced with the charger allowing the current to taper off
as the battery approaches full charge.
Stage 3 – Float; Finally, in the float stage the charger voltage is lowered
and held at a constant and safe predetermined level. This prevents the battery
from being overcharged, yet allows the charger to supply enough current to
make up for the self-discharge losses of the battery, while supporting any
additional loads connected to the battery (such as DC lighting and
refrigerators). This stage allows for the charger to be used as a DC power
supply.
Smart Charging Feature:
The ePOWER DC2DC+ Battery Charger will regulate its output based on the loads
connected to your battery bank. This function is important to maintain the
life of your battery bank as some battery chargers mistake loads for discharge
and continue to keep the batteries in the bulk or absorption stage for
extended periods of time, which will damage the battery bank. The ePOWER
DC2DC+ Battery Charger has two methods of load based regulation to ensure your
battery charger transitions to float when it should do so.
Features:
-Two totally independent DC Inputs for both engine and solar regulation charging one house battery bank output
- DC M6 screw terminals that will allow for large battery cable connection
between all sources
- A dedicated Maximum Power Point (MPPT) solar regulator
- The same battery algorithms as included in our AC mains ePOWER battery
charger. GEL, AGM, Flooded, Lithium and the ability to create a full custom
profile
- Vehicle input allows for either 12 or 24v and a maximum solar input of
45V/800W
- 40A output up to 40+°C with thermo controlled fan cooling
- Fully programmable LCD display to show which source is charging the battery
along with charger status, voltage and amperage
- Temperature sensor included in charger for more accurate battery charging
Victron BMV-712:
Bluetooth inside (Free programming guide attached in the download section):
With Bluetooth built-in, the BMV Smart is ready for the Internet of Things
(IoT) era. With Bluetooth being implemented in most other Victron Energy
products, wireless communication between products will simplify system
installation and enhance performance.
Download the Victron Bluetooth app:
Use a smartphone or other Bluetooth enabled device to
customize settings,
monitor all important data on single screen,
view historical data, and to
update the software when new features become available.
Easy to install :
All electrical connections are to the quick connect PCB on the current shunt.
The shunt connects to the monitor with a standard RJ12 telephone cable.
Included: RJ 12 cable (10 m) and battery cable with fuse (2 m);no other
components needed. Also included are a separate front bezel for a square or
round display appearance, a securing ring for rear mounting and screws for
front mounting.
Midpoint voltage monitoring:
One bad cell or one bad battery can destroy a large, expensive battery bank.
When batteries are connected in series, a timely warning can be generated by
measuring the midpoint voltage. Please see the BMV manual, section 5.2, for
more information. We recommend our Battery Balancer (BMS012201000) to maximize
service life of series-connected lead-acid batteries.
Very low current draw from the battery:
Current consumption: 0,7Ah per month (1mA) @12V and 0,6Ah per month (0,8mA) @
24V. Especially Li-ion batteries have virtually no capacity left when
discharged until low voltage shutdown. After shutdown due to low cell voltage,
the capacity reserve of a Li-ion battery is approximately 1Ah per 100Ah
battery capacity. The battery will be damaged if the remaining capacity
reserve is drawn from the battery. A residual current of 10mA for example may
damage a 200Ah battery if the system is left in discharged state during more
than 8 days.
Bi-stable alarm relay:
Prevents increased current draw in case of an alarm.
Other features:
Battery voltage, current, power, ampere-hours consumed and state of charge
