Commercial backup
When the grid stops, your business doesn't have to
Lost trading hours, spoiled stock, rebooting servers and diesel bills all add up. A three-phase hybrid system with lithium storage covers outages instantly and pushes the generator into a backup role.
01The problem
Why the usual fixes fall short
Many Ugandan businesses run a diesel generator as a daily power source rather than an emergency one. Fuel, servicing and the gap between an outage and the generator starting all cost money, and sensitive IT and POS equipment doesn't tolerate the interruption.
- Transfer gap drops POS, servers and routers
- Diesel and maintenance costs are unpredictable
- Generator noise and fumes affect staff and customers
- Three-phase loads need balanced backup
02Recommended architecture
How the system works
- Survey & load logging
Battery World engineers review your distribution board, phases and critical loads.
- Three-phase hybrid inverter
An LV or HV three-phase hybrid (e.g. Deye SG05LP3/SG01HP3, GoodWe ET) manages grid, generator, PV and battery.
- Lithium storage bank
A stackable LV bank or high-voltage battery sized to your outage profile.
- Generator as last resort
The inverter uses the generator input only when storage runs low.

07FAQ
Common questions
Can the system work with my existing generator?
Yes. Deye and GoodWe hybrids covered here include generator input or management, so the generator becomes a backup charger rather than the main supply.
Should I choose low-voltage or high-voltage batteries?
Below about 20 kW, 48 V (LV) stackable batteries are flexible and economical. Above that, HV batteries (e.g. Dyness STACK100/314, Deye GB-L) reduce current and cabling. Ask our engineers for a recommendation.
Do you provide a site assessment?
Yes. Commercial systems start with a site assessment. Request one through the commercial enquiry form or on WhatsApp.
