CDU considers raising plug-in solar inverter limit to 1,000 VA
The CDU/CSU parliamentary group is considering raising the permitted inverter output for plug-in solar systems in Germany from 800 to 1,000 volt-amperes.
The idea appears in an internal paper on changes to the Renewable Energy Sources Act, but it is not clear whether it is firm policy or only a proposal.
Many newer balcony solar systems include batteries, which are not clearly covered by current rules, and can connect several panels.
The group Balkon.Solar says a higher inverter limit alone may bring households little financial benefit because extra electricity could be sent to the grid rather than used at home.
It also warns that the change could conflict with an EU grid code and leave safety rules unclear.
The group proposes changing the rules for panel capacity and formally allowing systems that adjust electricity feed-in to household demand.
The proposal is part of a wider 86-point package on solar support, and it is not yet clear whether the governing coalition will back the package in parliament.
The CDU/CSU parliamentary group is considering raising the legal inverter limit for plug-in solar systems from 800 to 1,000 volt-amperes.
The proposal appears in an internal Union paper on a disputed amendment to Germany’s Renewable Energy Sources Act, but it is unclear whether it represents firm policy or an informal collection of ideas.
The group Balkon.Solar says the increase could bring little financial benefit to households and raises concerns about EU rules and safety requirements.
The proposal is part of an 86-point package that would also change support for solar power.
