ePower Chargers

We have been extremely impressed with the new ePower chargers, many great new features and a quality product designed for the marine and caravan market.

12Volt / 20amp - 40amp - 60amp - 120amp* (2 x 60amp units) 24Volt / 30amp - 60amp* (2 x 30amp units) Available in a few months

The Display Panel

The ePOWER Charger display gives you all the information you need for the operation of your charger. At a glance, key information such as charger amps, battery voltage and charge state continually alternate on the screen. When in float / power supply mode, the load amps are displayed so you can see exactly what the charger is doing. The display also allows you to program all settings of the charger, as well as activate the silent mode.

Silence when you need it – By pressing the “SEL” button for 5 seconds, the ePOWER Charger enters the ‘Silent’ mode that prohibits the fan from working. This ensures totally silent and safe operation at night, ideal if the charger is located close to your sleeping quarters. Silent mode limits current output to no more than 50%, and is programmed to remain on for 12 hours before automatically returning to a normal ‘fan-on & full output’ setting.

Multistage Charging Process

The Enerdrive ePOWER Battery Charger is a fully automatic, “set and forget” charger. It is designed to quickly and accurately recharge your batteries using algorithms that help maximise service life. Multistage smart charging technology enables the charger to be connected to your battery banks permanently.

As dictated by battery manufacturer’s recommendations, batteries require a multistage charge sequence for perfect, fast and accurate charging. Our ePOWER multistage smart chargers deliver four 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 capacity is recovered as fast as possible.

Stage 2 – Absorption Charge; With the charger voltage held steady the remaining 20% is replaced allowing the current to drop as the battery approaches its 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 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.

Stage 4 – Maintenance; This stage is a regular timed “return to bulk” stage. After 7 days of constant operation in “float” the Enerdrive ePOWER Battery Charger will switch the charger from float to bulk to agitate the batteries electrolyte helping to provide an extended service life.

Bank 1 PRIORITY – Charge Where You Need it Most

The ePOWER Charger delivers a priority charge to Bank 1, or your main house battery bank which allows the charger to get this bank recharged the quickest, then transition the cycle to the lesser bank 2 & 3 batteries. The priority function also allows you to have a battery chemistry different to the other two, such as an AGM battery for house and lead calcium for your start banks. In the event that all 3 banks are in need of a charge, an over-ride function helps recover all 3 banks quickly and evenly before switching back to prioritise on Bank 1.

It's All About Lithium

The recent advances in high capacity Lithium battery technology have seen the need to develop a battery charger suited to their needs. With most traditional ‘smart’ chargers their suitability to Lithium batteries is limited. Lithium batteries require a constant current / constant voltage charge algorithm and are unique in that almost every amp-hour of charge delivered by the charger is accepted as one amp hour into the battery, hence the need to deliver a constant current as long as possible.

The Enerdrive ePOWER charger can be programmed for Lithium batteries. This setting delivers the full rated output of the charger constantly with the charger switching to power supply mode once the voltage peak is met (indicating a full battery bank). The graph below shows the ePOWER charger algorithm perfectly supporting Lithium battery requirements.

ePower Inverters

Compact 400W, 1000W, 2000W inverter models that easily converts 12 volt (vehicle) power to 230 volt (household) power.

We have been very impressed with the ePower inverters, they offer very good value for money and all our in house testing shows them to be great quality.  

The Ready to Go inverter packages allow for quick installation of an RCD protected 230V circuit from you 12 volt power supply.  Only connection of the DC supply is needed.  They come on a sturdy powder coated frame, the 240V plug is locked so you cannot bypass the RCD and have a dual outlet GPO.

The Enerdrive ePOWER 400W, 1000W & 2000W true sine wave power inverter converts 12V battery power into true sine wave AC household power, allowing you to run loads up to 2000 watts. Electronic equipment and circuitry are designed to operate with a true sine wave, so most loads will perform better when connected to true sine wave.

With ePOWER’s state of the art, easy to use design, these inverters will offer you reliable service for providing AC power and 5V USB power for your home, boat, caravan, 4WD or commercial vehicle. The Enerdrive ePOWER Inverter can run many AC powered appliances when you need AC power anywhere. The 5V USB power can charge many USB powered devices.
