Hybrid vs Grid-Tie Inverter — Which Should You Choose?

A grid-tie inverter suits you if you’re not planning a battery and are happy exporting surplus energy to the grid — it’s cheaper and simpler. A hybrid inverter costs more but lets you connect a storage battery and gives you backup power when the grid goes down. If you want a battery now, or think you might want one later, choose hybrid.

What’s the Difference?

Both inverter types do the same core job — converting the DC power your solar modules produce into AC power suitable for your home. The difference is in what else they can do.

A grid-tie inverter only works together with the electricity grid. When your system produces more than you’re using, the surplus goes to the grid; when it produces less, you draw the shortfall from the grid. If the grid goes down, this type of inverter shuts off automatically, for safety.

A hybrid inverter can additionally manage a storage battery: it routes surplus energy into the battery and draws on it in the evening or at night. Many hybrid inverters can also provide backup power when the grid fails.

When a Grid-Tie Inverter Is Enough

A grid-tie inverter is the logical choice when:

• you use most of your electricity during the day, while your system is generating anyway;
• keeping the upfront investment as low as possible is the priority;
• you’re not planning to add a battery any time soon;
• your grid export terms let you effectively “bank” surplus energy and draw it back later.

It’s the simplest, and usually the cheapest, way to start using solar power.

When a Hybrid Inverter Makes Sense

A hybrid inverter pays off when:

• a significant share of your energy use happens in the evening or at night;
• you want backup power for short outages;
• you’re planning to add battery storage, even if not straight away;
• energy independence is a priority for you.

Even if you don’t buy a battery right away, a hybrid inverter keeps that option open without having to replace the whole system later. It’s a common compromise: you invest a little more in the inverter now, and add the battery when you’re ready.

When a Storage Battery Pays Off

A battery is the single biggest additional investment in the whole system, so it’s worth weighing up honestly whether it’s right for you.

A battery pays off faster if your consumption is concentrated in the evening hours, when there’s no sun, or if using your own generated energy directly is worth more to you than exporting the surplus to the grid. The added value is independence from short grid outages, too.

If you mostly use electricity during the day and your grid export terms are favourable, a battery will pay off more slowly. In that case, it’s reasonable to start without one, while keeping the technical option to add one later.

What to Choose: The Short Answer

It comes down to one question — do you actually need a battery, now or a few years from now? Here are specific models from our stock for the most common situations.

• No battery planned, lowest possible upfront cost. The cheapest way to start is the Deye SUN-4K-G06P3-EU-BM2-P1 three-phase grid-tie inverter, 4 kW — 599 €. A simple system where the surplus goes straight to the grid.
• Bigger house, bigger array, still no battery. The Deye SUN-6K-G06P3-EU-BM2-P1, 6 kW at 599 € or the SUN-7K-G06P3-EU-BM2-P1, 7 kW at 599 €. The price gap between power ratings is small, so it’s worth sizing for the array you actually plan to install.
• You want a battery now, or think you might later. The Deye SUN-5K-SG05LP1-EU-AM2-PLUS hybrid inverter — 999 €. The most common rating for an average household, and the battery can be added later.
• You want hybrid, but the budget is tight. The Deye SUN-3,6K-SG05LP1-EU-AM2-PLUS — 899 €. The smallest hybrid rating in our catalogue, suited to modest consumption.
• Your consumption is above average. The Deye SUN-6K-SG05LP1 hybrid inverter — 999 €. Extra headroom if a heat pump or an EV charger is on your list.
• Just testing solar with a couple of modules. The microinverters Deye SUN600G3-EU-230 at 209 € and Deye SUN800G3-EU-230 at 249 €.33. Not a whole-house solution — a way to start small.
• Choosing the battery separately. Storage options are in our battery category. Batteries are matched to a specific hybrid inverter, so it’s best to pick the inverter and the battery together.

We currently have 44 hybrid inverters, 13 grid-tie inverters and 2 microinverters in stock, all from Deye. One thing worth knowing: we do not sell solar modules. If you already have panels, or plan to buy them elsewhere, we’ll match an inverter — and storage, if you need it — to them.

Why buy from us: we are not VAT-registered, so the price you see in the catalogue is the final one — no VAT is added on top. Delivery anywhere in Lithuania is free, within 14 days. Returns within 14 days, with the return shipping paid by us. All equipment carries the manufacturer’s warranty and CE conformity. You can get a free consultation on sizing before you buy.

Frequently Asked Questions

Can I add a battery to a grid-tie inverter later?

Generally, no — a grid-tie inverter can’t manage a battery. If a battery is on the cards for the future, choose a hybrid inverter from the start.

Does a hybrid inverter work during a power cut?

Many hybrid inverters can provide backup power, but it depends on the specific model and installation. Confirm this feature before you buy.

Is a hybrid inverter a lot more expensive?

It costs more than a grid-tie inverter, but it gives you flexibility. If you’re genuinely not planning a battery, there’s little point paying extra for it.
