The performance of each solar home system will vary greatly based on the location where it is installed. If you need help sizing a Solar Grid Tie system for your home, check out our On Grid System Calculator

Each of these solar home systems are designed to provide you with the main components you will need to equip your home with a grid-tied Solar system that includes a back up battery bank. altE's Home Solar Systems include the major components needed for a solar installation. Since each installation is unique, some parts/materials will need to be purchased separately to satisfy the needs of your specific project and local regulations. If you experience frequent power outages but want to keep your connection to the utility grid, one of these systems might be just the thing for you! From premium modules and racking systems, to efficient inverters and durable batteries, these packages include high quality, safe components for your solar installation.  Also be sure to check out our Solar Rebates page where you can look up your state - you can save as much as 50% or more, in combination with the Federal incentives, on your installed system!

Radian GS4048A 4000W Inverter/Charger

The Outback Radian A series Inverter/Charger inherits the hallmark features of the original design including: Dual AC inputs for grid/generator flexibility; unparalleled surge capability and operational stability; easy field upgradeability and stacking capability for large systems; easy-to-use configuration wizard; and multi-mode operational flexibility.

Additionally, it has Advanced Battery Charging which allows it to support advanced technologies such as Lithium-Ion batteries and Grid Zero technology which makes it possible for a smaller inverter/battery system to perform like a much larger one, when required.

Features of Radian A Series include:

  • Grid-Interactive and Stand alone capability in the same package
  • GridZero Technology optimizes the balance between stored and renewable energy sources - minimizing grid dependence and allowing users to get the most out of their investment
  • Advanced Battery Charging (ABC) supports leading edge technologies including lithium-ion
  • Simplified stacking design for flexibility to upgrade to a 12kW system
  • Field adjustable input/output voltage and frequency boundaries
  • 120/240V Split-Phase Voltage
  • Dual AC inputs

Solar Charge Controller

Outback's FLEXmax Charge Controllers are the latest innovation in Maximum Power Point Tracking (MPPT). The FLEXmax's innovative MPPT algorithm is both continuous and active, increasing your renewable energy yield up to 30%. Thanks to enhanced cooling, the FLEXmax can operate at its full amp maximum current rating in ambient temperatures as high as 104°F (40°C).

Features of FlexMax 80 MPPT Charge Controller include:

  • Advanced Continuous Maximum Power Point Tracking Algorithm
  • Increases PV Array Output by up to 30%
  • Battery Voltages from 12 VDC to 60 VDC
  • Automatic Battery Voltage Detection at Start Up


The KiloVault 2100 PLC is a pure lead carbon sealed AGM deep cycle solar battery, for cycling applications.  KiloVault 2100 PLC is a cost-effective, maintenance-free battery that offers superior performance in Partial State Of Charge (PSoC) applications, combining pure lead and advanced carbon technology for extended battery life and rapid charging.  The batteries are designed for residential or light commercial off-grid, backup, or self-consumption applications.

This home solar system includes (8) 12V, 180Ah batteries, which will be wired together for a 48V, 360Ah, or 16.8kWh battery bank. Deep cycle batteries should not be discharged lower than 50%, so a battery bank of this size will provide approximately 4200 Watt hours (Wh) of energy per day, for two days when fully charged.  This is a rough estimate of capacity, actual capacity can change based on temperature, state of charge and the condition of the batteries. Additional batteries can be added to this system to increase the capacity of the battery bank.

Our grid tie with battery back up home solar systems include the basics that you'll need for your solar installation. In this table, we've listed a few more items that you may want to include with your package order. If you are interested in auto generator starts, mounting standoffs, or additional batteries and cables, this is the place to find them.
