Power converter on the Modular Scalable String Platform — hot-serviceable modules, N+1 redundancy and built-in GridMind AI, so a failed module is swapped without taking the plant offline
Three-phase hybrid inverter, 20–125 kW — MPPT solar, LFP battery, grid and generator in one unit, with a built-in static transfer switch that changes over in under 10 ms, so no external switchgear is needed
MPPT Solar Charger 1500Vdc for direct DC-coupled PV — 98% efficiency — 50-150 kW — array charges the battery with no AC conversion stage in between
Edge-native AI for load and solar forecasting with real-tariff dispatch — cuts diesel 18-40% in hybrid PV+BESS+Genset systems, and electricity cost 15-30% at grid-tied sites paired with BESS
8 industries — Factory, Telecom, Residential, Villages & Resorts, Utility/IPP, Hospital, Data Centre, Banking.
Factories pay two bills people overlook — energy (kWh) and a Demand Charge (kW) set by the single highest 15-minute peak of the month. LEONICS integrates Solar Rooftop + BESS + Modular PCS + GridMind AI: Solar clips On-Peak energy, BESS shaves the demand peak to cut Demand Charge 15-25%, and GridMind AI forecasts load and irradiance to dispatch the battery optimally — 30-50% lower total bills, 4-6 year payback, with CBAM-ready carbon reporting.
View details →Off-grid 4G/5G base stations and microwave repeaters burn 8,000-15,000 L of diesel per site per year — fuel logistics, theft, downtime and Scope 1 emissions are the real OPEX. LEONICS designs Solar PV + LiFePO4 + Hybrid Inverter so the generator runs only when it has to. How far fuel use falls depends on the tower load, how the PV and battery are sized, and the site's irradiance — for a 3 kW tower sized as in the worked example on this page, around 60-80%.
View details →Homes, apartments, and small resorts cut their daytime electricity bill 30-50% with a right-sized grid-tied rooftop system — installed by Microgrid Technology (a LEONICS company) and tracked via the Solar Insight Tool, with an optional battery for outage backup.
View details →Utilities and IPPs need MW-scale BESS for frequency regulation, capacity firming, and renewable integration. LEONICS delivers Modular PCS 0.3-3.2 MW + GridMind AI — and, for community energy, an Ethereum-based trading platform (GEMS) proven in Thailand.
