Midnite Solar Announced their new 10kw AIO at Intersolar Today

[Steve_S]

Why would you need to give up the classics?

AIO's have Solar Controller(s) and inverter/Charger built in. They don't use External Solar Controllers. The average cost of a Classic SCC is around $1K +/- if on sale & pending on location.

I'd love to test something like this but as a 24V System operator, I'm out.... Too bad really....
I HOPE that the AIO from Midnite will be able to interoperate with SmartBMS's like Speplos, Pace, JK-Inverter edition

Wow, love the PV start voltage and Arc Fault, Ground Fault and Rapid shut down included

Very nice! Looking forward to seeing some demos and reviews!

Right but theres nothing stopping you connecting additional external sccs to the battery bus. Especially if you already have them setup.

Must be low frequency?

More likely it is equipped with an autotransformer that shares the load...

 

[Hedges]

Here is the spec sheet for the new AIO

MPPT to 600V

Does this have "Hyper-Voc", protecting against damage up to Vpv = 600V + Vbat?
Or is 600V the maximum no-damage input voltage?

More likely it is equipped with an autotransformer that shares the load...

44kg, 98 lb.

Possible, but surge could be just big enough FETs and inductors.
Remember Rosie is spec'd at 200%, some data sheets say 300% surge.

Which is the definition of low frequency. When referring to AIO's.

 

[Mattb4]

Unless I am missing seeing it there does not seem to be a rating for idle current.

 

[Supervstech]

Not exactly.
Low frequency would have an full winding transfromer to boost the battery voltage to output voltage with a split winding mid point connection.

An autotransformer takes already boosted 240V and provifes a neutral.

No Hyper VOC so don't go over 600V
No Autotransformer it just has super surge

Well then, everyone else has had it wrong in this forum. Because every unit with a transformer is referred to as low frequency.
And 90% of them have autotransformers.

 

[timselectric]

I never really understood where the "low frequency" naming came from. The transformer changes the voltage, not the frequency.

 

[andrew-d]

Here is the spec sheet for the new AIO

Small typo: under "Operating Temperature Range", you have "(>450 derating)", which I assume is supposed to be "(>45C derating)", or "(>45º derating)".

Thanks for sharing!

Two different things being confused here yet again thanks to the wonky American split phase system.

 

[Hedges]

What we now call LF has an isolation transformer with battery voltage applied to primary, AC voltage on secondary.
I think my Sunny Island is 42V in, 170Vpeak out.

But these actually have HF PWM to synthesize sine wave.

What we call HF inverters just use inductor or HF transformer to create boosted AC voltage. Or, HV battery, just buck or buck-boost to AC voltage with HF inductor or transformer.

A true LF inverter would be MSW, like 12V applied to primary, 170V from secondary. Or multiple transformer taps to make staircase. Like early Trace and Warpverter.

Putting an auto-transformer or an isolation transformer after an HF inverter, inside or out, does not make it LF.
But when the transformer is step-up from 48V battery to 120 or 120/240Vrms, we call it LF. Not sure that is accurate.

Transformer does not do anything to provide high surge. MSW architecture does, limited I think to fault current capability of transformer (many times nominal.)

HF can have surge if transistors and boost inductor can deliver it. Usually limited in time due to heating.

What does split-phase have to do with it?
Transformers are used all over the world.

 

[Hedges]

No Hyper VOC so don't go over 600V

Can you roll out Hyper VOC with a firmware update?

Or is the MPPT not sufficiently configurable, or something like capacitors not rated for higher voltage?

 

[timselectric]

Transformer does not do anything to provide high surge.

It does, when referring to a single leg surge.

Spill the beans!

I think this was in reference to Monty Python and the Holy Grail
