100kWp Kankasundari Solar Mini Grid

Jumla, Karnali

In partnership with Sundrops Energy

Peak Power partnered with Sundrops Energy Pvt. Ltd. to design and build this 100 kWp hybrid solar microgrid for Kankasundari, in Jumla district, Karnali Province — a remote area where the existing grid connection is so poor and unreliable that it’s effectively unusable for day-to-day power needs.

The system combines AC-coupled and DC-coupled solar generation on a single hybrid platform. Two 50kW SMA Core1 Tripower inverters handle the bulk of the array on the AC side, while two Victron RS450 smart solar chargers add a further 20kW of DC-coupled PV directly onto the battery bus. Power is delivered through a three-phase grid-forming stack of six 15kVA Victron Quattro inverters, backed by a 96-cell 2V OPzV VRLA tubular gel battery bank for storage. The whole system is monitored and controlled through a Victron Cerbo GX with a Touch 50 display, alongside additional system control integrations built by Peak Power.

Power reaches the community over 3.86 kilometres of three-phase transmission line and a further 2.8 kilometres of single-phase line, connecting around 295 homes and 23 local businesses, along with the village clinic and the wider village area.

For a village where grid power exists on paper but is too poor in practice to rely on, this microgrid gives Kankasundari its first genuinely usable, clean electricity supply.
