Inverter for use with Stihl AL 500 Charger

[Billhook]

I have the Stihl 220 cordless and the AL500 mains charger.  Need it to be charged from a 12 volt inverter when in the woods

The AL 500 and batteries are very expensive and the charger sounds very sophisticated when running so there seems to be a choice between sine wave and square wave inverters.  I assume that sine wave is what is needed if there are delicate components and I was looking at a Krieger 1100 watt on Amazon for £90

i see the power consumption is 570 watts on the AL500

Has anyone had any issues doing this?

Def pure sine wave & I would say use a quality brand too.

 

Stihl missed a trick when they did not offer a 12v charger system.

 

 

i charge at home via an inverter but its 48v 10,000 watts

That Krieger looks like most cheap imports do.

 

A quality brand 1200 watts would be more like £400.

 

However you could use a low power one from a better make.

 

An 800w Victron at about £260.

What battery are you gonna run the invertor off?

 

Leave vechicle running?

Have you also looked at how quick you will flatten one 110ah battery?

 

At best you will get 1 hour of charge time to 50% SOC.

 

Less as you are pulling a big current.

So u live off grid?

That style of 12v plug is limited to 10amp / 120 watts & they get hot at that.

Yes. In a small woodland.

I was going to connect it to the Matbro heavy duty battery and if it turns out that it flattens it in a short time I will leave it running, obviously having a spare battery nearby while testing.

It is a long way to the nearest mains when down in the woods, and unnecessary to make extra ruts and lose a lot of time going back and forth.

If it all works out ok I will use the heavy duty leads bolted to the spare battery which can be taken to different machines so even the little Mule may be able to keep it going

it may work out cheaper just to run a Little Kawasaki 800watt generator which I have now I  think about it, in fact I will try that first and if it is not man enough, will look at an inverter.

Oooh if you've got a generator you could buy a 12v charger to keep the Matbro battery topped up.

Maybe not.
