Efficiency above 50% load is generally very flat. It's below 40% load that efficiency drops away. For some generators efficiency drop as...

Agree although I would say it's but one of multiple strategies required. Which is why I suggest keeping an eye on Australia (esp. Sth...

Aside from volt-watt, PV inverters should also have Volt-Var management, adjusting the level of reactive power generation as needed, be...

Rooftop PV plays a minor but important element in strategies for reducing carbon emissions, and enables use of an idle asset (rooftop...

That's for the grid's protection, not used as a tactical curtailment strategy. Tactical changes to demand and supply are used to adjust...

Or use a means to reduce exports, or even production, to zero during such times. My inverter has export control, should that ever be...

Pretty much all grid tied inverters have that but changing the grid's frequency is ASTONISHINGLY DIFFICULT and would never be a tactic...

People will buy them. There will be die hard off-grid lead acid set ups using 2V cells who need either more or replacement capacity. At...

The vast majority wouldn't. For those interested, watch the development on this stuff in the state of South Australia. They are the...

It probably won't need to get quite that high. Check the volt-watt requirements for grid-tied solar PV in California though, I don't...

You can if you allow grid voltage to rise high enough. Crude, indiscriminate as local voltages vary considerably, but it works. Better...

I note in recent days California's grid batteries have been discharging at 6+GW during the peak period and covering 25% or more of the...

I run a hybrid LiFePO4 and SLA battery so it is possible. However it depends on few things. Objectives? Type of lead acid battery and...

This morning I hooked up the spare AIO for charging the battery. Unfortunately it looks as though the comms in my AIO is toast. Comms...

No.

No. Not sold in Australia. In my case Solar Assistant communicates with my AIO inverter and also my Victron Smart Shunt for overall...

You sure are full of good ideas! I have a spare 4 kW AIO which can act as a charger. Indeed I recently hooked up this spare AIO to the...

It will depend on what data the Sol Ark supplies to Solar Assistant but I'd imagine that it would have AC input voltage and probably...

Apologies, just realised following is not specifically about Victron and regulatory issues but is following on from the discussion on...
