What is 4amps in watts?

[Carpmart]

There are only two 6A sockets on each of the boxes on the power pillars, rest are 4A. I was juggling usage whilst there on a 4A supply for 17 days. Bit frustrating TBH

It’s only around 220v at best too, so less Watts than you would expect. Exasperated further with voltage sag at various busy times of the day. My IP22 Victron charger really didn’t like the voltage sag…

We had a 2 amp hook up in Portugal once. Fridge and battery charger worked OK off it

In the nicest possible way looking it up on Google would have been quicker and less hassle.

I did but I also like answers from others as all you read isn’t always true, plus if we googled everything forums like this wouldn’t be as good.

Also it’s always fun reading different answers

Fair enough.

I have often wondered about the branding decision that resulted in them calling it the "Onan".

Onanism is, of course, wanking.

Named after Onan, in the bible, who rather than to impregnate his late brother's wife as custom dictated, "spilled his seed on the ground whenever he went in". This punishment was death.

I've always laughed about the branding

However, the number of times I've bailed out the solar boys in the Winter Snow

3 amp is quite common in Italy.

That's the beauty of the inverter charger with mains backup, you just set it down at say 3 or 4 amps so it won't take more than that from the hook up, the fridge can still do it's stuff and the kettle, microwave etc etc come off your inverter and batteries, batteries get recharged when no other demand.

Strange that the Victron chargers have a good input range from memory 180v- 260v ac so should not really be affected to much assuming it’s the 30a or less.

Yeah but it deffo didn’t like it in the evenings!

They are very good! May have to get one at some stage!

TBH, I very rarely plug in… it’s only a mixture of hookup being available (price inclusive) and time of year with low angle sun and VERY short days, that made me bother!

They are double wound auto transformers, low voltage input for too long, creates hysteresis and interruptions. Even a better toroidal found on all multiplus, can cope with low voltage compensated by the microprocessor on the output, up to a point. When harmonics build up trows a fit and disconnects.
What would be ideal, is, a true core type, where the windings are not electrically connected, and offers an isolation between primary and secondary coil. Then the incoming voltage does not matter as much.

I’m not sure if the multi plus has the same type of chargers fitted as the stand alone one, as I only use the stand alone one,
That being said you have far more knowledge on this subject than me, thanks for the explanation

Multiplus uses same transformer for stepping up (inverter mode) and stepping dowm ( charging mode), Is a bidirectional all switching is done electronically, and is a bidirectional inverter, hence can be grid connected and feed to grid and it can charge from grid. Another term for it is bimodal as it can do both modes.

4Amp! What they running there, bell wire??

I know the multiplus uses a toroidal (or did in my last one). But don't the IP range use a switched mode? They don't feel heavy enough to have a transformer (auto, dual coil or toroidal) in them?

My first job was at a Transformer factory so I still have a big interest in them

The one I took apart some time ago had a transformer. The IP rating, I have no idea as it's the last thing I'm interested in, unless it resides in harsh environment for any potential ingress. Referring to gear by IP is not very indicative because EVREY device that has switch gear inside and live terminals it has to have a minimum of IP2x, and IP4x if is a distribution or like a fuse board.

That is most surprising as the power fets and controller used in a smps are cheaper than an equivalent transformer at most sizes and linear psu's run hotter, are less efficient and heavier.

I think people refer to the Victron BlueSmart chargers by their IP numbers because they are the same charger in IP22, IP65 and IP67 casings.

Another thread off at a tangent as usual

4amps at 230v is 920 watts
4amps at 12v is 48 watts.

It’s like a game of top trumps.

I called it the IP range because that is the Victron product names. I thought it was an odd choice for a product name as I didn't know until a few weeks ago that the IP rating matches the product name.
