Enphase Energy, Octopus Energy announce UK partnership
Enphase Energy says that Octopus Energy’s retail customers will be able to integrate solar and battery systems into their energy plans in the UK market, with the introduction of Enphase IQ8 microinverters and the IQ battery 5P platform.
What could happen to solar inverters in case of high-altitude nuclear weapon testing
Researchers in the United States have investigated the sensitivity of PV inverters to the ectromagnetic pulses caused by high-altitude nuclear explosions during nuclear weapon testing. Their work presents several protection strategies aimed to improve the inverters’ immunity levels.

Cameroon exempts imported PV components from customs duties
PV modules, inverters, charge controllers, batteries and cables intended for rooftop solar systems will benefit from exemptions from customs duties until 2025.
Inverter undersizing not universally effective to reduce soiling losses
An international research team explained that, although inverter clipping is initially effective in mitigating soiling losses, these losses could become more visible with time, as solar module degradation makes clipping less frequent. They also warned that inverter undersizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.
