Grid-Tie Inverters

Direct answer: Grid-tie (utility-interactive) inverters convert PV DC to AC synchronized with the utility so you can offset loads and export when allowed. On this leaf, active stock is the Solis 16kW hybrid (battery-capable) plus Enphase IQ8 micros — both grid-interactive; classic pure-string GTIs are mostly archived. Choose hybrid when you want backup storage, or micros for panel-level AC. Call 877-878-4060 — DIY and pro installers since 1999.

Grid-tie (utility-interactive) inverters convert DC from your solar array into AC that syncs with the utility. They offset loads and, where interconnection allows, export surplus. Today’s ACTIVE grid-interactive options at altE are the Solis 16kW Hybrid Inverter and Enphase IQ8 microinverters — both interconnect with the grid; hybrid adds battery backup, micros add panel-level AC. Classic pure-string GTI models are being refreshed — call 877-878-4060 for a specific brand or kW size.

Grid-tie vs hybrid vs micro vs off-grid

  • Grid-tie / string — central inverter for a clean roof, no integrated battery. Surplus typically exports under net metering or similar programs. Many archived string SKUs live in this collection’s history.
  • Hybrid — grid interconnection plus battery charge/discharge and backup in one platform (example: Solis 16kW). Choose hybrid when you want storage or outage coverage, not bill offset alone.
  • Microinverters — panel-level AC (Enphase IQ8). Strong for shade, multi-plane roofs, and module-level monitoring; storage usually needs a separate Ensemble / System Controller path.
  • Off-grid — battery-based AC with little or no sell-back. Different interconnection and often a standalone charge controller.

What to buy with a grid-tie inverter

  • Solar panels — module Voc, Imp, and string count must fit the inverter MPPT or microinverter input window.
  • Cable & wiring — PV MC4 home-runs for string/hybrid; Enphase Q trunks for micros.
  • Solar panel mounts — roof or ground racking where the array and AC/DC home-runs land.
  • Monitoring & control — production meters, Envoy / gateways, and CTs for interconnection data.
  • Solar batteries — only when you choose a hybrid or micro + Ensemble backup path (not required for pure export-only designs).
  • Charge controllers — usually not needed when the hybrid already includes MPPT; relevant for DC-coupled off-grid add-ons.

FAQ

What is a grid-tie inverter?

A grid-tie (utility-interactive) inverter converts solar DC to AC that matches utility voltage and frequency so the system can power loads and, when allowed, export surplus. Unlike a standalone off-grid inverter, it expects a live grid reference for normal operation (unless it is a hybrid with a backup mode).

Do I need batteries with a grid-tie system?

No for bill-offset-only designs — surplus can export under your utility’s interconnection rules. Yes if you want backup or time-of-use shifting: choose a hybrid inverter (or microinverters plus an Enphase Ensemble path) and compatible batteries.

Why do hybrid and microinverters show in this collection?

Both architectures are grid-interactive. The Solis 16kW hybrid and Enphase IQ8 micros are the ACTIVE grid-capable inverters in stock. Pure string GTIs from the archive are being refreshed — call 877-878-4060 if you need a specific string model.

Grid-tie vs hybrid — which should I buy?

Pick grid-tie / string when you mainly want production and export with no storage. Pick hybrid when outages, self-consumption, or battery charging matter. Micros are a third path focused on panel-level AC and shade tolerance. Start at solar inverters if you are unsure.

Will a grid-tie inverter work during a blackout?

Most pure grid-tie inverters shut down when the utility is down (anti-islanding). Backup requires a hybrid with a backup/EPS output, a transfer solution, or an Enphase Ensemble-style system controller — not the string GTI alone. Call 877-878-4060 with your backup goals.

Can altE help size a grid-tie system?

Yes. Share your module list (or target kW), roof layout, utility interconnection notes, and whether you need backup. Call 877-878-4060 — DIY and pro installers since 1999.

How a Grid Tie Inverter Can Save You Money on Your Electric Bill

Are you looking for a way to save money on your electric bill? Installing a grid tie inverter is an effective and easy way to do just that. A grid tie inverter is a device that ties your solar power electric system into your traditional electricity meter, allowing your generated power to automatically detract from your own electricity meter. In this blog post, we'll discuss how a grid tie inverter can save you money on your electric bill.

What is a grid tie inverter and how does it work?

A Grid-Tie Inverter is an electrical device used to convert solar power into alternating current (AC) so that it can be connected to a utility grid. It is a necessary part of any solar system, as it provides the necessary power conversion from Direct Current (DC) to AC. Grid-tie inverters are also known as solar inverters, and are the most commonly used type of inverter in solar systems.

Grid-tie inverters typically have an input voltage range which depends on the size of the solar panel array, and an output voltage which matches the utility grid voltage. Solar Grid Tie Inverters can be used in conjunction with battery-based inverters, but don't have battery capabilities inherently. They are not suitable for standalone battery storage systems, as they do not provide energy storage capabilities. Grid-tie systems are used in homes and businesses that have access to a utility grid, as they allow users to save money on their electric bill by generating their own power.

The Benefits of Using a Grid Tie Inverter

Grid-tie inverters are a popular choice for those looking to install solar panels on their property. They offer an array of benefits that make them the preferred choice when it comes to solar power systems. With a grid-tie inverter, you can convert the direct current (DC) generated by your solar panels into alternating current (AC) that is compatible with the utility grid. This allows you to easily connect your system to the grid and start generating energy for your home or business.

One of the main advantages of using a Grid-Tie Inverter is that it eliminates the need for a battery-based inverter. Off-grid inverters require batteries in order to store any surplus energy generated from your solar panels, however a Grid Tie Inverter is designed to send any extra energy directly back to the utility grid. This means that you don’t have to worry about buying and storing batteries, which makes for a much more efficient system overall.

Another benefit of Grid-Tie Inverters is that they can use transformerless inverters. These inverters provide a number of advantages including greater efficiency, lower costs, and less weight compared to traditional transformer-based inverters.

Grid Tie Solar Inverters Simplify and Reduce Costs of Going Solar

A grid tie inverter is significantly simpler and less costly than an off-grid inverter. Furthermore, a grid-tie system is simpler and less costly than an off-grid system overall.

A grid tie system essentially consists of just four major components in addition to the wiring:

By contrast, off grid inverter systems require the addition of solar charge controllers, battery bank and additional overcurrent protection and wiring.
