Your photovoltaic (PV) system generates your own renewable electricity, during the day, but how about your night-time usage? Thanks to technological advances, now it’s possible to stock up on the energy your PV system generated during the day-time, to use it even when the sun’s not shining.

Home energy storage batteries can help you cut your electricity bill significantly, especially if you have a high night-time electric usage (consult this information on your invoice, given to you by your electric supplier – we can explain this information on your bills to better advice if this is the solution for you). Since you live in a sunny country like Portugal – when the sunlight is FREE – why not use it for your own purpose?

It can, however, be difficult to choose the right brand or model, in this sense, Casa Verde’s preferred choice is LG because of their long warranties, durability, high testing standards, reliability for the future, research, and development patents, technological advantages, and much more.

Why you can feel assured with your choice of LG

The units of battery storage from LG are a complete solution with LG-made parts starting from scratch (the battery itself, and its components), providing one solution with one warranty. With LG Chems (battery storage division), as a partner, Casa Verde offers a true one-stop solution – from the idea conception phase, though consulting, to design, with safety assured by certifying bodies – Casa Verde can assist you every step of the way.

LG is focusing its energy business on the next-generation growth engine. LG is the only company that has comprehensive business capabilities in the entire stage of the energy value chain: Generation, Storage, Efficient Use, and Management. LG is one of the world’s leading companies with top-class technology and product line-up for each segment: Energy generation (High-Efficiency solar cell) and Efficient Use. Now LG introduces the home energy storage system (ESS) that maximises the value of a home owner’s Photovoltaic (PV) system.

If you have solar PV, you can generate plenty of electricity when the sun is shining. But on overcast days you’ll make less, and you’ll make none at all at night. This generation pattern often doesn’t match up with when households want to use electricity - it’s at night when you want the lights on and to use appliances like a dishwasher or TV.

Adding battery storage minimises your reliance on the grid, and reduces the money you put in your energy supplier’s pocket.

Why should you have a home battery from LG?

Use all of your solar energy - self-consumption
As we explained before, typical homes have high energy demands in the mornings and evenings but solar generation is highest mid-day. Without a home battery, the solar energy produced in the daytime would be wasted. A home battery allows you to store solar energy and use it whenever you need it.

Cut back on your electricity bills
By fully using your solar energy, you will significantly cut back on your electricity bills, since your batteries will charge during off-peak times.

Three-phase DC couplet
LG ESS is a DC-couplet system that uses a simpler energy conversion process for greater energy efficiency – up to 3%. Compared with the AC-couplet product, it operates more simply and needs no PV inverter, saving on installation costs (since the solar panels and battery share the same inverter) and time. In addition, LG ESS has a 3-phase connection to prevent power imbalance and overload, so it is able to supply power more steadily.

It’s easy
Manage your battery storage with EnerVu. A mobile application that’s user-friendly, enables you to check self-consumption rate, PV generation, feed-in electricity, load consumption, charging/discharging, and much more.

Lithium Battery Cell

Compactness & Long Lifespan
LG Chem’s L&S (Lamination & Stacking) process minimizes dead space and enables higher energy


LG Chem’s SRS® (Safety Reinforced Separator) increases the mechanical and thermal stability of battery cells. Stacking process minimizes dead space, enables higher energy density and enhances the sustainability of cells structures.
Why should I choose LG Energy Solution over other home battery manufacturers present in the market?

Unlike other home appliances, a home battery is a product you would be using for about a decade (or more).

What battery capacity do I need?

Like solar PV, customer desires and needs, affect the answer. A larger battery can keep the house running and charge your electrical vehicle, run your pool heating pump or even keep a simple light on overnight. Everything depends on your specific energy needs Casa Verde can create the perfect solution specially tailored for you.

Let our specialized team help you ease your electric bill with the energy of the sun, during the day with a solar PV system, or at night, with battery storage, it’s FREE energy after all.
