\n

A 5 kW inverter is the size most Ukrainian households land on when they want to run the real house through a blackout, not just the essentials. It is enough to keep a fridge, lighting, a water pump, a boiler, and a normal load of electronics going at once, without the cost of a much larger unit. Genixgreen has built LiFePO4 energy-storage systems in its own factory since 2011, and this page explains what a 5 kW-class hybrid inverter actually runs, what to check before you buy, and which of our units fits the 5 kW class. If you are deciding between sizes, our 3 kW vs 5 kW inverter guide<\/a> compares them directly, and you can see current specifications on our product page<\/a>.<\/p>\n\n

The short answer: is 5 kW right for you?<\/h2>\n

A 5 kW-class hybrid inverter suits a typical family home that wants most of the house running during an outage: a fridge, lights, a router, a television, a water pump, and a gas boiler, with room for a kettle or a washing machine at times. It is the right size when 3 kW would leave you switching things off to avoid overload, but you do not need to run heavy simultaneous loads like air conditioning plus a pump plus an electric cooker together. If your loads are lighter, our 3 kW inverter guide<\/a> may fit better; if they are heavier, an 8 kW unit gives more headroom. The key is to size to your real loads and their startup surges, not to a round number.<\/p>\n\n

What a 5 kW inverter runs at home<\/h2>\n

A 5 kW continuous rating covers a lot of a normal home at once. As a rough picture, a fridge, a dozen LED lights, a router, a television, a laptop or two, and a gas boiler’s pump and controls together sit well under 2 kW, which leaves comfortable headroom on a 5 kW-class unit for a water pump or a washing machine to cycle. What eats the budget is not the count of devices but the big simultaneous loads: an electric kettle, an immersion heater, air conditioning, or a well pump running at the same time. The way to know your own number is to add up the continuous watts of everything you would genuinely run together, which our inverter sizing guide<\/a> walks through.<\/p>\n\n

Continuous vs. surge power<\/h3>\n

The rating on the box is the continuous power, but the number that decides whether the inverter trips is the surge. Motor-driven appliances, a fridge compressor, a water pump, a washing machine, pull several times their running wattage for a split second when they start, an inherent property of electric motors<\/a>. A 5 kW-class inverter needs surge headroom above its continuous rating to absorb that spike without cutting out. It is also worth remembering that appliance labels sometimes list volt-amperes rather than real watts, and the two differ once power factor is counted<\/a>, so size with a margin.<\/p>\n\n

A practical margin rule<\/h4>\n

Do not allocate the full inverter rating to planned continuous loads. Keep headroom for motor starts and for appliances that may overlap unexpectedly.<\/p>\n\n

Why single-phase, 48 V and pure sine wave<\/h2>\n

Three specifications separate a home-ready 5 kW inverter from a generic one. It should be single-phase at 230 V, which is what a Ukrainian home is wired for. It should be a 48 V unit, so it pairs with a modern LiFePO4 home battery. And it must output a genuine pure sine wave, the clean waveform that motors, compressors, and sensitive electronics need; a modified or square wave makes them run hot and can upset boiler and appliance controls, as our gas boiler backup guide<\/a> explains. A grid-interactive hybrid inverter also has to disconnect safely from the grid during an outage so it never energizes a dead line, a behavior set by interconnection standards<\/a>. Our inverter types guide<\/a> covers the hybrid, off-grid and grid-tie distinction.<\/p>\n\n

Matching a 5 kW inverter to your battery<\/h2>\n

An inverter’s power decides what you can run at once; the battery decides for how long. A 5 kW inverter paired with a small battery will run big loads but only briefly, while the same inverter on a larger battery carries a lighter load through a long outage. That is why the two are chosen together: pick the inverter for your peak load and the battery for your runtime. Our battery runtime guide<\/a> shows how to turn your loads and desired hours into a battery size. Because our batteries are 48 V LiFePO4, a 5 kW-class 48 V hybrid inverter pairs with them directly.<\/p>\n\n

What we stock in the 5 kW class<\/h2>\n

Our hybrid inverter range runs from 5.5 to 8 kW, single-phase 230 V, all matched to our 48 V LiFePO4 batteries. For the 5 kW class, the natural fit is our 5.5 kW single-phase unit, which carries a genuine 5 kW-class load with surge headroom to spare and includes a built-in MPPT solar charger, so it runs solar, battery and grid from one box. If you expect to add a larger solar array or heavier loads later, the 8 kW units, one with dual MPPT and one with a generator input, give more room.

Frequently asked questions<\/h2>\n\n

Is a 5 kW inverter enough for a house?<\/strong>
\nFor most family homes, yes. A 5 kW-class hybrid inverter runs a fridge, lighting, a router, a television, a water pump, and a gas boiler together, with headroom for a washing machine or kettle at times. It is not sized for several heavy loads at once, like air conditioning plus a pump plus an electric cooker, so size to your real simultaneous loads.<\/p>\n\n

What can a 5 kW inverter power?<\/strong>
\nA typical mix of a fridge, LED lighting, a router, a television, laptops, and a boiler’s pump and controls sits well within 5 kW, leaving room for a pump or washing machine to cycle. The limit is big simultaneous loads such as an electric kettle, immersion heater, or air conditioning running together.<\/p>\n\n

Do you sell a 5.0 kW inverter?<\/strong>
\nOur closest unit to the 5 kW class is a 5.5 kW single-phase hybrid inverter, which comfortably covers a 5 kW-class load with surge headroom. Rather than a fixed 5.0 kW model, we size to give you margin for motor startups. You can see it on our product page.<\/p>\n\n

Does a 5 kW inverter need a special battery?<\/strong>
\nIt needs a matching 48 V battery. Our 5 kW-class hybrid inverter is a 48 V unit and pairs with our 48 V LiFePO4 home batteries. Choose the inverter for your peak load and the battery for how long you want to run.<\/p>\n\n

Is a 5 kW inverter better than 3 kW?<\/strong>
\nNot better, just bigger. A 5 kW-class unit runs more at once and suits a full family home, while a 3 kW class suits a smaller home or apartment running essentials. Our 3 kW vs 5 kW guide compares them so you can match the size to your loads.<\/p>\n\n

The right next step<\/h2>\n

A 5 kW-class hybrid inverter is the size that keeps most of a Ukrainian home running through a blackout, as long as you size it to your real continuous and surge loads, insist on a pure sine wave, and pair it with a 48 V battery. To compare it against a smaller unit, read our 3 kW vs 5 kW guide<\/a> or our 3 kW inverter guide<\/a>; for the buyer’s checklist, see our inverter buying guide<\/a>; and to see the 5.5 kW unit and request a quote, visit our product page<\/a>.
