What Solar Installers Have to Solve

PV Without Storage Leaves Energy on the Roof

Rooftop solar generates when most homes are empty. Without battery storage, that excess energy either exports to the grid at a falling feed-in rate, or is simply lost. Battery storage closes the day-night gap — and that's where installers add real value.

Day/Night Load Mismatch

Homes are empty when the sun is strongest. Without storage, solar is generated when nobody is home to use it.

Falling Feed-In Tariff

Many markets pay less for solar exports than they charge for grid imports. Storing PV is now more valuable than exporting.

No Standard Battery Packs

EPCs need easy-to-spec, easy-to-install, expandable battery products with complete technical documentation.

Customer Sizing Confusion

End customers see capacity numbers without understanding how PV, inverter, battery and load must match — installers have to educate.

How Solar Battery Storage Works

From Daylight Generation to Evening Use

Solar generates on its own schedule — your home uses energy on its own schedule. Battery storage bridges the gap. Three time windows describe the full daily energy flow.

DAYTIME
Generate & Store

PV panels generate DC power. The inverter supplies daytime home loads first. Excess solar charges the LiFePO4 battery instead of being exported at low feed-in rates.

EVENING
Switch to Battery

As PV generation falls below home demand, the system blends solar and battery output. Peak-rate grid imports are replaced with stored solar energy at zero marginal cost.

NIGHT
Battery Powers the Home

With no PV generation, the battery supplies overnight loads — fridge, lights, Wi-Fi, standby — until depleted. Grid is only drawn upon if needed.

Why Add Battery to Residential Solar

Four Reasons Installers Quote Battery on Every PV Project

Adding storage to a residential PV system raises project value, raises self-consumption ratios, prepares the home for outages, and protects the customer against falling export tariffs.

Higher Self-Consumption

Lift self-consumption from typical 25–35% (PV only) to 70%+ when battery storage absorbs daytime surplus for evening use.

Lower Grid Import

Cut evening peak-rate grid purchases. Stored solar replaces high-priced electricity drawn from the utility after sunset.

Higher Project Value

PV-only quotes are commoditizing. PV + battery packages raise installer revenue per project and improve close rates.

Outage Readiness

A battery installed for self-consumption is already there when the grid drops. Backup becomes a free secondary benefit.

Battery Size by Solar Project Type

Match Battery Capacity to PV System Size

A general installer rule: 1.5 – 2 kWh of battery per 1 kW of PV for healthy self-consumption, adjusted for evening load. Four common pairings cover most residential projects.

Entry
kWh Battery
0

Pairs with 3 – 5 kW PV

Small homes, low evening load, single-floor apartments. Modest self-consumption boost on a tight budget.

Mainstream
kWh Battery
0

Pairs with 5 – 8 kW PV

Standard 3–4 bedroom homes with typical evening cooking, lighting and entertainment loads. The most common spec.

Premium

0

Pairs with 8 – 12 kW PV

Larger homes, higher evening load, electric cooking and heat pump backup. Strong self-consumption ratio.

Project Grade

Large residences, villas, light-commercial PV, EV charging integration. Stackable expansion path.

Solar Storage FAQ

Questions From Solar Installers & EPCs

The questions we hear most from rooftop PV installers, EPC partners and solar distributors evaluating battery storage.

How does residential solar battery storage work?

Solar panels generate DC power during the day. An inverter converts it to AC for home loads. Excess solar power that isn't consumed immediately is stored in the LiFePO4 battery. After sunset or during low-light hours, the home draws stored energy from the battery instead of importing from the grid — increasing self-consumption and reducing electricity import.

Yes — that is the primary use case. During the day, excess PV generation charges the battery. In the evening and overnight, when PV generation drops to zero, the battery discharges to cover home loads. With a properly sized battery, most evening and overnight loads can be supplied from stored solar.

A common sizing logic is: roughly 1.5–2 kWh of battery per 1 kW of PV for self-consumption, adjusted for daily evening load. Typical homes pair a 5–10 kWh PV system with 10–15 kWh of battery. Larger PV systems (10 kW+) often use 15–25 kWh stackable battery storage. Send your PV size and average daily evening load and we'll recommend a matched battery capacity.

Yes. Existing PV systems can be retrofitted with battery storage in two ways: (1) DC-coupled — adding a hybrid inverter that combines PV input and battery management; (2) AC-coupled — adding an all-in-one battery+inverter unit downstream of the existing PV inverter. Our 3kW/5kW all-in-one and stackable systems support both retrofit paths.

For a new PV + battery installation, a hybrid inverter is usually the cleanest single-system solution — it handles PV MPPT, battery charging/discharging and grid interaction in one box. For retrofits onto an existing PV inverter, an AC-coupled battery+inverter is often more practical. Our stackable and all-in-one systems include built-in pure sine wave inverters covering both cases.

Yes. We supply residential solar battery storage to solar installers, EPCs and regional distributors with standardized product portfolios, full technical documentation (datasheet, manual, certification, MSDS, wiring diagrams), OEM/ODM private label, sample-to-bulk processes and 99.89% on-time delivery for project-grade orders.
