The modern blueprint for home backup power in Jamaica is battery-first: a hybrid inverter with lithium storage switches over in milliseconds when JPS drops, runs the house silently, and — unlike a generator — earns its keep every ordinary day once panels are added.
The blueprint, layer by layer
Layer 1: hybrid inverter (6kW–12kW, J$220,000–J$430,000). The brain — manages grid, battery and future panels, and hands your circuits to battery instantly during outages.
Layer 2: lithium storage (10–16kWh, J$360,000–J$450,000). The muscle — sized to run fridge, lights, fans, router and TV through an evening outage and beyond.
Layer 3: solar panels (605W, J$25,000 each). The income — recharges storage free daily and cuts the JPS bill 70–90%, converting backup insurance into a 3–5 year-payback investment.
Sizing backup honestly
List what must stay on and for how long. A 10kWh battery carries typical essentials overnight; AC-heavy homes step up to 15–16kWh or dual batteries. The free calculator does this arithmetic for you.
Battery-first vs generator-first
Generators cost every running hour and announce every outage to the street. Batteries are silent, instant and fuel-free — and the panels they enable turn the whole rig into a money-saver. Keep a small generator only as a long-storm backstop if you wish.
FAQ
Can I start with just inverter + battery, no panels?
Yes — that is the classic staged path; panels bolt on later without rework.
How fast is switchover?
Milliseconds — computers and routers never notice.
