PV mini-grid to back Congolese agriculture
Equatorial Power and SustainSolar are installing containerized, off-grid solar battery power systems to support farming projects on an island in Lake Kivu.
The best string configurations to avoid mismatch losses from rooftop PV shading
Researchers in Pakistan have evaluated the impact of shading on inverter set-ups to assess PV system performance. Tests were conducted on a 51 kW system featuring SMA inverter topologies but the researchers say the findings could be applied to products from other manufacturers. The results showed the number of maximum power point trackers is important but levelized cost of energy calculations are also crucial to selecting the right inverter configuration.
Product recall: SMA calls in MLPE over rapid shutdown problem
The inverter maker conducted tests and found the branded SMA TS4-R-F-42 could not always supply the rapid shutdown function called for by a new U.S. safety standard when applied in commercial and industrial systems featuring its inverter tech.
