SolarEdge Nexis Battery

SolarEdge is a global solar technology company with more than 3.7 million residential and commercial installations worldwide totaling over 52.6 GW of capacity (as of 2025).

Unlike traditional string inverters - where all panels in a string are limited by the weakest-performing panel - SolarEdge uses a system of Power Optimizers attached to each individual panel, feeding into a central SolarEdge string inverter. The Power Optimizer is a DC-to-DC converter that continuously monitors each panel's voltage and current output and adjusts them individually before sending conditioned DC power to the central inverter. This means shading on one panel does not drag down the output of every other panel in the string. The result is more reliable energy production, panel-level monitoring, and built-in safety via the SafeDC™ feature.

According to a 2025 independent study by VDE Renewables, SolarEdge's optimizer-based systems deliver up to 10.5% more energy than standard string inverter installations on typical residential rooftops with uneven shading or non-ideal orientations.

SolarEdge Nexis is designed for both new solar installations and retrofit applications. It supports DC-coupled and AC-coupled system designs, which gives installers more flexibility when adding battery storage to a home.

Compatibility depends on the existing solar equipment, inverter setup, electrical panel, available space, and backup goals, so an installer should review the home before confirming the best design.

A SolarEdge residential installation follows these general steps:

1. A certified installer designs the system using SolarEdge's Designer software tool, specifying panel layout, optimizer models, inverter size, and wiring configuration.
2. Permits are pulled from the local authority having jurisdiction (AHJ).
3. Panels and optimizers are mounted on the roof - each optimizer is physically attached to the back of or near each panel.
4. The central inverter and Gateway are mounted on a wall (typically in the garage or utility room).
5. DC wiring from the optimizer strings runs to the inverter.
6. The inverter connects to the main electrical panel.
7.  After a utility inspection, the system is activated and commissioned in the SolarEdge monitoring platform. The full process from contract signing to activation typically takes 4-12 weeks, with most of that time spent waiting for permits and utility approval rather than actual installation work.

SolarEdge ONE is SolarEdge’s energy management platform. It helps optimize how solar energy is used, stored, and managed based on battery charge level, utility rates, household energy needs, and backup preferences.

Through compatible SolarEdge equipment, SolarEdge ONE can help improve self-consumption, manage battery operation, prepare for outages, and coordinate connected energy devices.

SolarEdge ONE supports several energy management modes configurable through the mySolarEdge app:

Maximize Self-Consumption: The system prioritizes using solar energy to power your home, then stores excess in the battery, then exports to the grid. Battery discharges to cover home loads when solar is insufficient, before drawing from the grid. This mode maximizes the value of self-generated energy.

Time-of-Use (TOU) Optimization: SolarEdge ONE automatically schedules battery charging and discharging based on your utility's rate schedule, storing cheap off-peak energy and discharging during expensive peak hours. Can also schedule grid charging during off-peak periods if economical.

Backup Only: The battery is held fully charged as a backup reserve and only discharges during a grid outage.

Weather Guard Mode: Automatically triggered when severe weather is forecast; charges the battery to 100% regardless of other mode settings. Returns to normal mode after the weather event passes.
