Yes. We supply customers and installers across Uganda. Delivery and installation arrangements depend on location, so tell us your district when you enquire.

Yes. Installers, EPCs and resellers can apply through the Partner page for trade support, technical documentation and project assistance.

A hybrid inverter combines a solar charge controller (MPPT), a battery charger/inverter and grid/generator management in one unit. It decides moment to moment whether your loads run from solar, battery, grid or generator.

Low-voltage (LV) batteries run at a nominal 48–51.2 V and suit most homes and small businesses. High-voltage (HV) batteries stack modules in series to hundreds of volts, which reduces current, and suit larger three-phase and commercial systems. An LV battery only works with an LV inverter, and an HV battery only with an HV inverter.

Check your meter and distribution board. Most homes in Kampala are single-phase. Many businesses, larger homes and all industrial sites are three-phase. Three-phase sites need a three-phase inverter to back up all phases.

DoD is the share of a battery's capacity you can use regularly. A 5.12 kWh battery at 95 % DoD gives about 4.86 kWh of usable energy.

LiFePO₄ (lithium iron phosphate) batteries support far more charge cycles, deeper discharge, faster charging and need no maintenance. Datasheets for the batteries we list rate them at 6,000 to 10,000 cycles depending on model.

Yes. Every hybrid inverter we list has built-in MPPT solar inputs. You can start with grid-charged backup and add panels later within the inverter's PV limits.

Warranty terms are set by each manufacturer and sometimes vary by country. Examples from the datasheets: Deye hybrid inverters, 5 years (up to 10 years depending on installation country); Dyness PowerBrick Plus/Max/SC and STACK100/314, 10 years; Dyness DL5.0F, 7 years (10 optional). See each product page and the Warranty page.

Use the Warranty Support form with your serial number, invoice and a description or photo of any error codes. We coordinate diagnostics and the claim with the manufacturer.

It uses standard sizing maths (running load, surge, battery depth of discharge and Uganda solar hours) and recommends only products in our catalogue with published compatibility. Treat it as a well-informed estimate. A site survey confirms the final design.
