In designing a bespoke power system for a client from Lekki, Lagos, our engineers recommended and used:
Six (6) 300W monocrystalline solar panels connected in two (2) strings of three (3) panels each. Total output from solar panels expected at 1.8kW.
A 3.5kVA Cobalt inverter.
Four (4) Ritar AGM batteries, at 48V. The four batteries were mounted on a rack.
A 60A Epever MPPT charge controller. Read why Epever charge controllers come highly recommended here.
Typically, before designing the system, a power audit was done to determine the peculiar energy needs of the client. There were also considerations of the amount of grid power available to the client. Installation space and the client's budget were also considered during the initial consultation and design.
A grid-tied installation to offset the deficit, all the components were slightly oversized to give the customer the opportunity to slightly expand the load independently without adding a new component or incurring extra installation costs.
A circuit breaker was added between the charge controller and the panels to make it easy and safe to disconnect the system from the panels in the case of emergencies like lightning that could damage the inverter or solar panel fires.
Designed with building space in mind, the solar panels were mounted on the roof and the batteries, charge controller and inverter installed in a corner of a non-living area of the house.
SolarKobo helps its clients in Lagos and elsewhere in Nigeria make the best possible choice of all solar products including batteries, solar panels and charge controllers. We also have university-trained engineers who provide the best possible installation services on order.
