Solar Generator und Mobile Steckdose mit 230V Akku

If you want to use a 220V device away from a socket
, you need a mobile socket with a 230V battery – but
actually doesn't have many cheap options to choose from. I have found two good ways of actually realizing
such a scenario with a “230V battery”. I have been looking for a good 230V
battery for a relatively long time to be able to operate a label printer that is attached to a netbook and barcode scanner
in a warehouse. A generator is out of the question here, as
the exhaust gases indoors are a no-go. I don't think this scenario is that far-
fetched. But even in a tent or when camping without a shore connection
or in a micro camper, a 230V battery socket can be very useful overnight as well as during the day
. After all, compressor refrigerators, notebooks, camera
batteries and smartphones always need to be charged outside – not
to forget the light at night. So I am very surprised that
there are very few useful products for this.

Because of this, I want to introduce all of my like-minded people to
my solution that I have found that actually works. While searching, I came across a total of 2
reliable solutions. One of them is the SUAOKI 400Wh 230V battery
with pure sine wave. The nice thing about it is: You can simply
buy a suitable solar module and in the simplest way you have a completely
self-sufficient small solar power island system. Here you can see the pure sine wave of the SUAOKI
PSB5. Clean 50Hz at 229V. This is extremely important for electronic devices that are
connected to this 220V battery, because with an unclean sine wave – which is
also called a modified sine wave – many power supplies cannot cope
or even break! What is not irrelevant is the fact
that the SUAOKI battery has two real Schuko sockets and not just strange sockets that are
very unsafe for children. If you look at a Goal Zero Yeti 400, for
example, then you can almost even grab the 230V contacts with adult fingers. Children's fingers fit easily through the openings.

You will now surely ask yourself what
you can connect to such a 230V battery and how long does it last? In principle, you can connect anything that
consumes less than 300W of power to it. This can be a compressor refrigerator, notebook,
camera battery charger, drone or smartphone. In order to be able to compare the endurance of the devices with each other
, I decided on a uniform test that looked like
this: I take a 70W consumer and measure how long the battery lasts until nothing works
. The built-in battery in the SUAOKI has an output
of 36Ah at 11.1V – that is 399Wh. In theory, 70 W would last 5.7 hours. However, the converter does not have 100% efficiency
and so it comes to 4 hours and 20 minutes in my test. That was then an effective 324Wh and thus approx.
83% of the stated capacity of 400Wh. This is perfectly fine, as the 324Wh can support you
long enough during the night. If you still need more than 400Wh of power,
SUAOKI has a larger battery at the start.

Namely the SUAOKI G500. It is basically the same device in a
larger case to stow a larger battery . When looking for a suitable battery, you will
at some point ask yourself whether it would not be cheaper to build such a battery
yourself? Simply connect a voltage converter 12V 230V to
a car battery and that's it. The fact is that you need a good converter,
a good battery and a very good charger. There is also a stable housing
in which you have to safely assemble the individual parts yourself. I've tried it and can assure you
that the individual parts you need for it wo n't be cheaper. The biggest advantage of the SUAOKI 230V batteries
compared to self-made solutions with lead or AGM batteries is completely different: They
are the low-maintenance and light lithium- ion (li-ion) batteries. This makes the device much lighter
– 6kg instead of 11kg in my do-it-yourself solution. In addition, you can use the full 36Ah here,
while AGM batteries end at around 50% power. So if you still remember the bill,
then with my do-it-yourself solution with an AGM battery I would only get 216 Wh and would only be able to maintain
the 70W power for 3 hours instead of the 4 hours 20 with the SUAOKI.

There is also an LCD display that shows the exact state of charge of
the batteries. So not just a “green” for ok, “yellow”
for half and “red” for all. This way you can estimate much better
how long the battery will last and how long it still needs to be recharged. If you are interested in the details of
the do-it-yourself solution, take a look at the top of the info card.

I linked a post to you in
which I wrote about which parts were necessary..
