Hybrid solar for a home with power cuts
If your home loses power often, a hybrid solar system is the one that keeps the lights, the fans, the router and the refrigerator running when the grid fails: it adds a battery and a hybrid inverter to the rooftop array, and the battery carries the circuits you choose through the cut. An on-grid system cannot do that, because it switches itself off during a power cut by design. KTronics installs hybrid systems for homes across the Colombo, Gampaha and Kalutara districts with its own engineers, and island-wide beyond them.
Why a hybrid system, and not on-grid
An on-grid system, also called grid-tie, has no battery. It feeds the grid under the utility agreement, costs the least per kilowatt, and switches itself off during a power cut — by design, so that it cannot energise a line someone is repairing. If the supply fails often, that is the moment it is no use to you.
A hybrid system adds a battery and a hybrid inverter. It stays connected to the grid, keeps chosen circuits running through a power cut, and can hold daytime energy for the evening. The current feed-in schedule also sets a higher rate for new battery systems on the units they export in the utility's priority hours.
Which circuits stay on
The battery and inverter are sized from the loads that must stay on and for how long, not from the roof. The essential circuits — typically lighting, fans, the router, the refrigerator and a water pump — are wired to the backed-up output of the hybrid inverter; heavy loads such as air conditioning and water heating, which would drain a battery quickly, stay on the grid supply. Which circuits go on which side is decided with you at the survey, and it sets the battery capacity and the inverter size.
Still a grid-connected system: Net Plus and the clearance
A hybrid system stays connected to the grid, so a new one connects under the Net Plus scheme like any other rooftop system. The Ministry of Energy's directive of 11 September 2026 made Net Plus the only scheme for new rooftop solar agreements and closed Net Metering and Net Accounting to new applicants. Under Net Plus the solar system has its own export meter; every unit it generates is sold to the utility at a feed-in rate set by the Public Utilities Commission, and the electricity you use is billed separately at the normal tariff.
It starts online, with a capacity clearance: in the EDLCare customer portal at edlcare.edl.lk for a CEB-area supply, or in LECO's Solar PV Capacity Clearance System at solar.leco.lk where LECO supplies you. We prepare and submit the request for you; what we need is a photograph of both sides of the account holder's national identity card and a recent electricity bill. The connection sets the ceiling on the system: as a guide, the utility approves about 5 kW on a 30 A single-phase connection.
What happens after handover
The system is connected to our own monitoring platform for the term of the maintenance agreement. Systems on it are read daily, faults raise an email when they happen, and every Sunday you receive what your system produced that week, that month and that year. Monitoring is tuned to catch a system that has stopped or thrown a fault; a system quietly producing less than it should is found at the annual inspection or by reading the weekly report.
Ten years on every device we supply, and that is our own undertaking rather than a manufacturer's term passed on. Under the maintenance agreement we respond to a reported hardware breakdown within six hours, an authorised person attends site within three working days, and where the failed part is one we stock we aim to resolve within five working days.
Equipment chosen for the house
Equipment is chosen for the site, not for a distributorship: hybrid inverters from Solis, Deye, Solax, GoodWe, Growatt, SMA and Must; panels from Jinko, JA Solar and Longi; protection from Phoenix Contact, zBeny, Schneider and Chint. Batteries are lithium iron phosphate (LiFePO4), a chemistry built for thousands of charge cycles and safe and stable for daily use.
What we need from you
- A recent electricity bill for the house
- A photograph of both sides of the account holder's national identity card, for the capacity clearance request
- A list of what must stay on during a cut, and for roughly how long
- Photographs of the roof and the distribution board, which make the first conversation a great deal shorter
Based in Kelaniya, with our own engineers covering the whole Western Province — the Colombo, Gampaha and Kalutara districts. Beyond it we work island-wide, with projects delivered as far as the Galle and Kandy districts.
