Drop in technology

[Mrcoolabah1au]

How the technology going are the worth the effort asking for a friend with no great need for 240 v other than laptop and small microwave

The "small microwave" will use twice the rated heating power in actual electrical power .... so a 1000w microwave requires 2000w @ 240vac, so add 10% for the inverter losses = 2200w divided by 12vdc = 185 amps. So you are looking for a drop in that will supply 185 amps minimum for a continuous ... say 10 mins. That is only 30Ah of capacity and nothing for a quality 100Ah lithium battery, but for the quality you get in a drop in battery .... depends on just what you buy and how they measured the battery capacity. A quality lithium battery is measured at a load that would see it go from 100% SOC down to 0% SOC in 2 hrs, so a continuous 50 amp load for a 100Ah battery, yet is could deliver 200 amps for around 30 mins before the same 0% SOC was reached.
So, if the drop in can deliver 200 amps for 30 mins, it will do just fine ..... but then you need to look at the $$ and see if it is still in the price range .....

Thanks but do not think technology is there yet

You can buy drop in batteries that will do that job, but the price will take your breath away. Cheaper for us to build a 100Ah battery and minimum control system all in a box that can be installed in place of the existing battery. We are experimenting with the Electrodacus SBMS0 controlling various relays that could separate the charging from the load so each were turned off as required rather than either on or off like the drop ins are now. The Hino is the guinea pig for this experiment, the last 120 amp all in one unit cost us a set of cells barely 12 mths old, so testing can be expensive

Your accountant should be advising you of R&D tax relief and other gov't grants.

Some one got to start the ball rolling with experimental stuff and then for the good the bad and the ugly

Hmm..... an oxymoron within and oxymoron, an accountant giving useful advice about a govt department actually being helpful ...... as in "how to make a struggling small business; start with a successful mid size business and ask an accountant to run it for you in the way they think it should be run"
&
"I'm from the govt, I'm here to help you"

My experience in the past regarding accountants, you run your business your way and then get them to translate it into the best method of minimising tax and possibly getting some money back ....after they take their cut of course ....

As far the tax dept and associated departments, better to beg for kindness than actually tell them what you plan to do because it will be illegal by the time you actually try to claim any benefit you might have received ......

I shudder just thinking about the number of businesses that have gone belly up because they continued on believing all they were doing in the R&D field was tax deductable, only to have that knocked back at the last post and still have to pay the full tax assessment the tax dept decided they should pay .... based on all the info they received in good faith in the R&D claim, especially when I was one of them .....

Not our experience, it's all in the wording. We used an 80 YO advisor who wrote the application in pencil ! Kept crossing out and replacing words as he knew from long long experience exactly what they wanted to hear.
But I believe it has all changed now ?

[jon_d]

Correct.

Same as dealing with overseas departments in an international organization. Just say the right words that they are looking for. If they are not there, they can't tick the box.

Simple really....

You can spend your life fighting people/organisation believing you're right and expecting them to bend to your opinion. Or you can change your approach and do it the way they need you to do it. They have their rules set by higher up the ladder.

Trying to argue with the lower order people is expecting them to go and argue your position with their boss to get an exemption to the process..... Good luck with that.

Gotta tell you, I don't have anything to do with that side of the business, I'm just an unpaid volunteer, Margaret's business so her responsibility, so I'll pass the advice on and she can decide what she wants to do about it.
