A complete answer to Zanzibar's power challenges
Zanzibaba Project Solutions designs and installs complete power solutions for Zanzibar properties where grid interruptions can affect comfort, security, guest experience, and business operations. We combine solar PV, lithium battery storage, generators, hybrid inverters, ATS changeover, monitoring, and maintenance into one reliable system sized for your actual loads. Complete power solutions in Zanzibar: solar systems, lithium battery backup, generators, hybrid power, ATS installation, monitoring and maintenance.
01
One Integrated Power Strategy for Zanzibar
Reliable power is not simply a matter of adding solar panels. We assess your grid supply, essential and non-essential loads, peak demand, operating hours, available roof or ground space, and the level of autonomy your property needs during an outage.
The result is a coordinated power system for villas, apartments, offices, shops, restaurants, hotels, and resorts across Unguja — designed to reduce downtime, fuel consumption, and the risk of equipment damage caused by unstable supply.
02
Solar PV & Hybrid Inverter Systems
We deliver rooftop and ground-mounted solar systems, MPPT charge control, hybrid and grid-tied inverters, distribution protection, surge protection, earthing, and remote production monitoring. Systems can be designed for daytime savings, full off-grid operation, or dependable backup during ZECO outages.
Every design is based on a load assessment rather than a generic package, so the panel array, inverter capacity, cable sizes, protection devices, and future expansion allowance work together safely.
03
Lithium Battery Backup, UPS & Critical Loads
Battery storage keeps essential circuits running silently when the grid fails. We separate and prioritise loads such as lighting, Wi-Fi, refrigeration, CCTV, gates, pumps, point-of-sale systems, servers, and selected air-conditioning so available energy lasts where it matters most.
Solutions range from compact home and office backup to modular lithium battery banks for hotels and commercial operations, with automatic transfer, battery management, safe isolation, and clear runtime expectations.
04
Generators, ATS & Automatic Changeover
For high-power equipment, long outages, or sites requiring guaranteed continuity, we supply and integrate petrol or diesel generators with automatic transfer switches (ATS), changeover panels, sound attenuation, exhaust routing, fuel planning, and electrical protection.
An existing generator can often be integrated into a modern hybrid system. The generator then runs only when batteries reach a defined level or demand exceeds the solar and storage capacity, reducing fuel use, noise, and unnecessary engine hours.
05
Hybrid Solar + Battery + Grid + Generator
A hybrid system gives Zanzibar properties the strongest balance of reliability and operating cost. Solar carries daytime loads and charges the batteries; batteries bridge normal outages; the grid supports the system when available; and the generator remains a final layer of protection for extended interruptions or unusually high demand.
We program operating priorities around your goals — lowest fuel cost, maximum battery reserve, uninterrupted hospitality service, or staged backup for critical and non-critical circuits.
06
Monitoring, Maintenance & Future Expansion
Remote monitoring makes it possible to track solar production, battery state, consumption, alarms, and generator operation. We also provide preventive maintenance, fault diagnosis, battery health checks, panel cleaning guidance, generator servicing coordination, and system optimisation.
Systems are documented at handover and can be designed for expansion as a villa adds air-conditioning, a hotel adds rooms, or a business increases its electrical load.

Power solutions FAQ
Which power solution is best for Zanzibar's frequent outages?
For most properties, a hybrid system combining solar panels, lithium batteries and the grid provides silent daily backup and lower operating costs. Hotels, restaurants and larger commercial sites may also need a generator with ATS as a final backup for long outages or heavy loads.
Can you connect solar and batteries to my existing generator?
Yes. We can assess compatible generators and integrate them with a hybrid inverter or automatic changeover system. The control strategy can start the generator only when battery levels or electrical demand require it.
How do you determine the correct battery and inverter size?
We conduct a load assessment covering appliance wattage, start-up currents, operating hours, critical circuits and desired backup duration. This determines the inverter rating, usable battery capacity, solar array and generator support required.
Do you provide generator-only and battery-only backup systems?
Yes. We provide standalone battery backup, UPS systems, generator installations, ATS panels, solar-only systems and fully integrated hybrid solutions. The right option depends on the property, loads, budget and required uptime.
Do you support hotels, villas and businesses across Zanzibar?
Yes. We design, install and maintain power systems for homes, villas, apartments, offices, retail, restaurants, boutique hotels and resorts across Unguja, with site assessment and coordinated commissioning.
