Hybrid PV systems with LiFePO4 storage: your building runs on the sun first, draws on the battery at night or during outages, and uses the SOMELEC grid or generator only as backup.
Request a studyWhatsAppPanels + hybrid inverter + LiFePO4 battery for homes, zawiyas, clinics, hotels and mining camps.
Extend the autonomy of an existing system: compatibility check (voltage, BMS, inverters), added batteries and panels.
Sized for maximum autonomy, air-conditioned nights included, with grid or generator as simple backup.
Commissioning, user training, remote monitoring, maintenance and repairs.
Consumption, bills, priority loads and site constraints.
Sizing, production and savings estimate, detailed quote.
Supply, mounting, protections, earthing and commissioning.
Training, remote monitoring and maintenance contract.
Engineering support, independent from equipment sales if you prefer. For individuals, companies, hotels, clinics and private industrial sites.
Needs, load profile, PV, battery, inverters, yield estimate.
Analysis of SOMELEC bills and diesel use, savings opportunities.
Supplier selection, datasheets, compatibility, logistics and formalities support.
Second opinion on a quote or an existing installation.

ETS KHALIHANNA is led by Khalihanna Maelainine, energy engineer with an MBA and a former assistant professor specialised in photovoltaic materials research. An engineering approach adapted to Mauritanian heat, sand and coastal wind.
A hybrid system uses solar and battery first and keeps the SOMELEC grid or generator as backup. Off-grid runs without the grid and needs more battery and panels.
Long life, deep discharge and safe chemistry, well suited to hot climates.
Often yes, if the new battery is compatible (same voltage and cell count, BMS, inverter). We check before any purchase.
Every project is sized to your consumption. We provide a detailed quote after the site visit.
Yes, anywhere in Mauritania (e.g. Nouadhibou), depending on the project.
