Frequently Asked Questions About 6KW Solar Packages
This collection includes two distinct types of systems. The grid-tied kits, including the APSystems DS3 and Solis 7.6KW packages, are designed to reduce your utility bill by feeding solar power back to the grid. They do not work when the grid goes down and are not off-grid power solutions. The off-grid kits, including the EG4-based packages and OMO Stacking System configurations, are fully independent from the utility grid, include battery storage, and operate during outages. If you are buying this system for a property without utility service, a rural homestead, or a backup system that works when the grid fails, you need one of the off-grid configurations. Call us if you are unsure which direction fits your situation.
At 6.6kW, you are producing enough daily energy to run a full household with few compromises. Refrigerator, chest freezer, washing machine, well pump, a mid-size mini-split for heating and cooling, lighting throughout the home, electronics, and regular power tool use in a shop or garage are all realistic at this system size. What still requires planning is running multiple large loads simultaneously. The inverter capacity determines what you can draw in any single moment: the EG4 6000XP handles up to 6,000 watts continuous, the EG4 12000XP doubles that, and the dual OMO Stacking System delivers 11,000 watts at 120/240V. A 6.6kW array with 10 to 15kWh of battery storage covers a well-run off-grid home through most of the year in the Midwest and through most of winter in the South and Southwest.
The dual OMO Stacking System pairs two 5500W inverters together to produce 11,000 watts of combined output at both 120V and 240V split-phase. Everything stacks vertically, batteries add modularly, and the system has a compact footprint that works well in a utility room, garage, or outbuilding. The EG4 kits are component-based and offer their own advantages: purpose-built off-grid inverters with sophisticated generator management, more detailed monitoring, and strong field support. The EG4 12000XP in particular delivers 12,000 watts continuous, exceeding the dual OMO stack. Buyers who prioritize a clean, space-efficient installation lean toward the OMO Stacking System. Buyers who want maximum output or plan to run very heavy simultaneous loads tend to prefer the EG4 12000XP.
It depends on the AC unit and how you define running it. A central HVAC system with a 2 to 3 ton compressor draws 2,000 to 4,000 watts running and surges significantly higher on startup. A 6.6kW solar array on a sunny day produces enough to run a unit in that range during peak sunlight hours while still charging the battery bank. The challenge is overnight cooling and consecutive cloudy days. For reliable central AC off-grid at this system size, you need a large battery bank of 20kWh or more, a high-surge inverter like the EG4 12000XP, and a generator available for extended bad weather. Most off-grid customers at the 6kW level who want reliable cooling opt for a high-efficiency mini-split instead, which delivers better efficiency per watt and is far more manageable on a battery bank overnight.
Yes, OMOSolar offers solar financing options including FIGURE HELOC, which you can find on our financing page. On the federal tax credit: the Residential Clean Energy Credit currently allows you to claim 30% of the cost of a qualifying solar and battery storage system on your federal taxes. Off-grid systems can qualify, but the rules have nuances. Batteries paired with solar panels that charge primarily from solar typically qualify. We recommend confirming your specific situation with a tax professional since eligibility depends on how the system is installed and used. The tax credit combined with the long-term elimination of a utility bill makes the 6kW tier one of the strongest value propositions in our lineup for buyers committed to full energy independence.
