long-term dataset from a residential PV-battery system in Yangon

Fourteen months of sub-hourly data were collected from a residential PV\u2013battery system in Yangon, Myanmar (UTC+06:30), logged at 5\u201310 min resolution. The raw archive includes 104,036 timestamps across day and night. For analysis, only periods with nonzero PV output were retained; key-channel gaps were dropped; and all times were aligned to local time, yielding 56,623 daytime records. Power series were integrated over each time step to form daily energies (kWh). Unless noted, grid power > 0 indicates import and battery power > 0 indicates discharge.
