Wood Mackenzie is forecasting that an EU funding ban on projects using solar inverters from China and other countries deemed high risk will impact 14% of EU solar demand through to 2030, as well as 12% of energy storage deployments.#EnergyStorage #Europe #Inverters
Ban on high-risk PV inverters to impact 14% of EU solar demand to 2030 - pv magazine Global -
The EU moves to ban high-risk inverters from China.
The European Commission will gradually eliminate the use of Chinese-made inverters in EU-funded energy projects, a major step aimed at protecting critical energy infrastructure from possible cyber threats that could trigger power outages.
An EU official stated that ‘serious’ economic and cybersecurity threats had been identified.

US Warns Hidden #Radios May Be Embedded In Solar-Powered #Highway Infrastructure - Slashdot/
The 4-page #security note, said that undocumented cellular radios had been discovered "in certain foreign-manufactured power #inverters and #BMS ," referring to #battery management systems.
The note, which has not previously been reported, did not specify where the products containing undocumented equipment had been imported from, but many inverters are made in #China.

Very sketchy #reuters story: “rogue communication devices not listed in product documents have been found in some Chinese #solar power #inverters by U.S experts (…) including cellular radios, have also been found in some batteries from multiple Chinese suppliers (…) Reuters was unable to determine how many solar power inverters and batteries they have looked at.”
Its is totally unclear in which batteries produced by which companies delivered to whom had these modems (?) and if they were on, had SIM cards and so on.

So, a friend of mine who lived #OffGrid in #Vermont had one of these set up. Definitely make sure you have secure connections and test everything (more than once)!
How to Build a #BicycleGenerator

"The intention of this project is to build a straight forward #HumanPowered generator from a used bicycle and to use it to power light bulbs, blenders, cell phones, laptops, and other small appliances. This project will help one develop engineering skills while learning about a clean way of generating electricity.
"The project was created as part of Infrastructure Academy's environmental technology curriculum for high school students, so it is intended to be both achievable and affordable.
"Before continuing with the actual bicycle generator, one should understand how it works, and the components that make it up."

Beim Hersteller des PV-Wechselrichters ein Ticket aufgemacht, wegen eines unter Last/Wärme lärmenden Lüfters. Erst aktive Kommunikation, dann ~10 Wochen ohne Reaktion.
Jetzt: „Wir senden ihnen gerade einen neuen Wechselrichter zu“. 😲
Natürlich nicht zum Elektriker, sondern zu mir.
Mal schauen was dann noch so passiert. -

The other problem w/ #Vance’s critique is that he ignores that many provisions in the #IRA have sparked a manufacturing boom in the #UnitedStates — also designed to counter #China’s dominance in the #green #energy arena. Besides EVs, the bill included tax incentives intended to spur manufacturing of #solar modules, #wind turbines, #inverters, #EV batteries & power storage, & the extraction & refining of critical minerals.

Got home late last night and the inverter failed when the wife turned on the induction hob. Turns out the 125A MCB breaker feeding the inverter decided to fail.
Opening it up shows the contacts and conductive braid were badly discoloured from constant heavy loads like car charging.
I swapped it for a new one (thank goodness for spares) and had everything back up in 10 minutes but I think I'll be replacing it with a MCCB in the near future.

Some inverters have large input capacitors and can draw an inrush current of several thousand amps when the breaker is switched on. This can destroy the breaker contacts. If high inrush currents are encountered consider putting an appropriately rated resistor across the breaker contacts to precharge the capacitors before the breaker is operated.

Lesson learned: If you have a large inverter you need some way to pre-charge the capacitors before connecting LiFePO4 batteries so that the BMS doesn’t shut the battery down due to inverter inrush current. My temporary solution is to use an AGM battery to charge the caps before shutting the battery disconnect. Permanent solution will be installing a current surge limiter. #lifepo4 #inverters #rvlife
