Residential Solar System

SunWell's Residential Solar System series turns a house into a self-running energy site without the trial of mixing separate components. Instead of sizing panels, a reserve, and a converter on your own, you receive one engineered package matched to your roof, your routine demand, and the backup you expect. A recently launched cabinet line folds the reserve and conversion into a single enclosure, shortening setup and reclaiming floor space. Most packages push live status to a handheld device.

Selection Guide

Residential solar systems bundle solar generation, battery storage, and inverter control into one home energy solution. Start by listing your critical loads and the backup hours you need during an outage: a typical home covers lights, refrigerator, router, and pumps with 5–10 kWh, while whole-home comfort with air conditioning or well pumps usually needs 15 kWh or more. The all-in-one families — APOLLO A, APOLLO B, APOLLO C, and ARES — span about 5.12 kWh to 30.72 kWh per unit, with inverter power from 5 kW to 12 kW and parallel expansion available for larger homes; APOLLO units use 51.2 V LiFePO4, while ARES adds mobile 25.6 V / 51.2 V options. The ESS, MA, and PA lines round out the range and share the same hybrid or off-grid topology.

Decide whether you need grid-tie, off-grid, or both: ESS and MA support hybrid operation with automatic transfer, while PA is positioned for off-grid use. Check the PV input voltage and MPPT range against any existing panels, and confirm the IP rating if the unit sits outdoors — many residential units are built for sheltered indoor, garage, or covered-outdoor placement, so verify the exact rating on the product page. All-in-one units communicate over USB and RS485 (BMS); ESS, MA, and PA add Bluetooth, WiFi, or optional GPRS, so pick the monitoring method that fits your site. Finally, verify surge power for the heaviest motor (pump or AC) rather than just the continuous rating, and favor a system that accepts extra battery or solar modules if your usage may grow.

Frequently Asked Questions

How much battery capacity do I need for a home backup system?

Add the wattage of every device you want to back up and multiply by the hours each runs overnight or during an outage. A basic home with lights, fridge, router, and a few outlets typically needs 5–10 kWh, while whole-home comfort with air conditioning or pumps often needs 15 kWh or more.

Can a residential solar system work off-grid?

Some models are designed for off-grid use, while others are hybrid systems that can operate with or without the grid. If off-grid is your primary goal, choose a model explicitly listed as off-grid and verify that its inverter, charge controller, and battery capacity can handle your entire load profile.

What PV array voltage is compatible with these systems?

Models in this range cover MPPT ranges from about 60 Vdc up to 950 Vdc depending on the model. Check your existing panel string voltage against the system’s MPPT range and maximum PV open-circuit voltage; mismatched strings can damage the inverter or void the warranty.

Can I monitor the system remotely?

Most residential systems support Bluetooth and WiFi, and several also offer GPRS or RS485/CAN integration for third-party monitoring. Remote monitoring is useful for tracking solar production, battery state of charge, and fault alerts from a phone or web dashboard.

Are these systems safe to install outdoors?

The majority of residential all-in-one systems in the range carry IP65, which protects against dust and low-pressure water jets. They can be installed outdoors under a shelter, but you should still avoid standing water, direct sun exposure where possible, and ensure adequate airflow around the unit.
