Problem: The starting current briefly demands more than 2000W.
Solution: if more power is demanded, the device limits the output to 2000W, then to 1000W after a few seconds. Some loads with electric motor require very high starting currents for a very short time, then drop to lower consumption. Therefore, the current limitation of the device only affects the start-up phase of the consumer, which can lead to stuttering or out-of-round start-up.
Unfortunately, all battery-powered units, as well as diesel units, have to contend with this problem. Fortunately, with the E-Series, several units can be connected in series to extend the capacity. Another way to extend runtime is by connecting one or more solar panels. Especially when the sun is shining and the sky is blue, electrical devices can be operated longer and in an even more environmentally friendly way.
“The costs are very high for the low energy. A diesel genset with the same power costs only a fraction and usually runs longer.”
A diesel genset should not necessarily be compared 1-to-1 with our battery storage solution. The E-Series offers quiet and emission-free power delivery. This is not possible with a conventional genset. Gradually, regulations in more and more inner cities are limiting the use of fossil-fueled generators and requiring battery-powered units. In addition, the low initial costs of the gensets are offset by significantly higher operating and maintenance costs. In many cases, our E-series is more economical than the dirty alternative after just a few years.
Batteries and high-quality power electronics with a transformer coil entail a certain amount of weight – there’s no getting around that. However, to make transporting the E-Series easier, we have developed accessories that make moving the unit much easier: the steel frame expands the possibilities to grip the unit and is also sturdy enough to allow the E-Series to be lifted by a crane or forklift using textile hoists or chains. In addition, there is the possibility to order the E-Series with large solid rubber tires (diameter: 26 cm), which allow transport even in demanding terrain. In this case, the frame is equipped with two additional foldable handles that enable “wheelbarrow-like” movement of the device.
“The product is interesting, but we are waiting until battery prices come down and the technology matures.”
The technology is already mature. With our high-quality power electronics and long-life LFP batteries, the E-Series already has an advantage over diesel and gasoline generators (see question on cost). The first restrictions and bans on diesel-powered equipment are being introduced, and diesel prices will continue to rise as well. An investment in battery-powered equipment is already paying off and will become even more attractive as fuel prices rise. And beyond that, in few areas is there “the right moment” to switch to environmentally friendly alternatives. Active climate protection is needed immediately – on a small and large scale.
“The unit is quiet, however, that’s not much of an advantage when I’m using it to run a loud demolition hammer.”
That’s right. Of course, the rest of the advantages such as the avoided exhaust gases and diesel savings remain. However, during the operation of a demolition hammer, it will be noisy even with our E-Series. However, experience shows that diesel generators are often not only turned on while the equipment is in use, but also left on during breaks in between for convenience. Basic noise that can be prevented with our E-Series.
“We have already had bad experiences with rechargeable batteries. The effective capacity was already greatly reduced after a few uses and the device was thus useless.”
We have often heard about bad experiences with battery-powered tools or small powerbanks. One more argument in favor of our E-Series: unlike most smaller, older battery-powered devices, we use lithium iron phosphate battery technology, which is characterized by its high cycle stability. That means even after 2,000 charge cycles, an effective capacity of more than 80% should be available in most cases. Even with a daily charge of the battery, the device can thus remain ready for use for over 6 years.
As with most mobile power generators in this power class, the ARVEY E series has a so-called IT network. This type of network does not have an earth conductor and has the advantage of fast commissioning and maximum availability of the power supply. The special safety requirements of this type of network are taken into account in the E series: In the ARVEY E5, each socket is protected by its own RCD (residual current device).
Longer storage of the device
Before prolonged storage, the unit should be fully charged and the battery disconnect plug disconnected. Because batteries self-discharge over time, and deep discharge will cause irreparable damage, so recharge the device every 4-6 months.
Inadvertent deep discharge due to non-use and non-charging is the reason for 95% of all battery defects. This device and its batteries will last the longest if you use it often.
Do not freeze the battery: Lithium batteries should never be exposed to temperatures below -10°C for an extended period of time.
Do not overheat the batteries: Overheating the battery above +50°C is as harmful to the battery as hypothermia. So place the device in the shade if possible, and be careful about leaving it in the car at the height of summer.
Do not short the battery: Never make a conductive connection between the positive (red) and negative (black) battery terminals. This will inevitably damage the battery and pose a risk to your health.
- Car/Motorhome/Train: When not in use, the device should be switched off with the battery disconnect plugs disconnected.
- Aircraft: According to the current status of IATA regulations, the following criteria must be met for transport in an aircraft:
- the battery should be discharged to 30% charge.
- the device must be packed according to regulation UN3481, PI 967 Section I.
- the necessary warning labels must be applied to the packaging
Please contact your airline in advance to avoid problems at check-in.
Third party accessories such as solar panels or wind turbines can be used on the ARVEY A1 as long as they meet the specifications for renewable energy sources:
- Max. Input voltage: 48V Voc
- Max. PV module voltage: 40V
- Recommended input voltage: 30V
- Minimum input voltage: 27V
- Max. Input power: 800W
ARVEY can be charged from all possible power sources – solar, mains, car battery, cigarette lighter, wind turbine, etc.
The charging time to fully charge is 5 hours at 0.25C. The battery can be charged even if the battery disconnect plug is disconnected.
Charging time with simultaneous use of ARVEY
Simultaneous use, i.e. discharging, and charging of the battery is possible in principle, but has a negative effect on the life cycle of the battery. It does not matter whether charging is done via the mains plug or via a solar panel.
The supply duration by ARVEY, depends mainly on the energy consumption of the connected device.
Three main units, voltage (V), amperage (A), and power (W), are required to calculate the useful life.
The formula is composed as follows: W = V * A
Capacity of ARVEY battery: 480Wh (20Ah capacity * 24V voltage)
This means, you can use the battery for one hour with a consumption of 480 watts. Accordingly, a device with 1000W can be operated for about half an hour.
Depending on consumption, the power capacity of ARVEY results in: 24 hours of cool food , watching TV for 7 international games, drilling 400 holes 6cm deep in concrete.
Technically, it is possible to connect several consumers to the ARVEY at the same time, as long as the total demand of the devices remains below 1000 watts. However, it must not be two devices for 230 V mains voltage, i.e. no TV and hairdryer at the same time. The use of this combination is at your own risk and may cause damage to the device, which is not covered by the warranty.
Problem: The polarity of the connected battery unit is incorrect.
Solution: Immediately disconnect the battery disconnect plug and contact customer service.
Problem: Many devices whose “end product” is heat (some types of hairdryers, kettles) or they need heat for functionality, such as printers, need very high peak currents, some of which can be 7 times the rated power. This makes them special consumers whose operation cannot be guaranteed with this device.
Problem 1: The cable polarity is wrong.
Solution 1: Check polarity.
Problem 2: The connecting cables may be damaged.
Solution 2: Replace the cables or use a different power source.
Problem 3: Internal fuse.
Solution 3: Contact your nearest AXSOL certified service center.
Please ensure that the contents of the packaging (see manual p. 24) are complete and check all parts for visible damage. Remove all parts from the packaging and remove all packaging parts from the device.
When you receive your device, the battery disconnect plug is disconnected to prevent unnecessary self-discharge. Before operating the device, please place it on a flat surface to prevent it from tipping over. Make sure that the surface can support the weight of the device.
To use the device, connect the battery disconnect plug. Please fully charge the battery before using it for the first time.
The illustrated version can be found in the manual on p. 24.
