Hi I’m new here. I’m getting quotes for an off grid system for a local sporting club.
I have a quote from a company for a system that comprises 18 x 550watt panels, a Deye 8kw single phase inverter and a 10kw battery in a metal cabinet, including solar panel rails and brackets but no installation. $21.6k what do you think?
and are Deye inverters suitable for off grid use.
Yes, the Deye inverter is one of the few hybrid inverters that will work off-grid without a problem. The price is very reasonable for a system of this size and type.
The question is whether this system is suitable for your loads and requirements. It is not a very big system, so I’m assuming the loads are not very large at the sporting club.

thankyou for your reply and the information. I also read your Deye Inverter review which was very good. We are looking at replacing our current small system which is 1030ah at 24 volts and only 1.5kw of solar. The Club doesn’t have large loads, we want to run a couple of fridge’s, a security and alarm system, a small very compressor intermittently, for a couple of hours, 3 days a week, a microwave for less than 1/2 an hour in total intermittently over 3 days a week and if possible a 7kw inverter split system air conditioner a couple of hours a day mid summer, 3 days a week and the same mid winter for heating.
Pros: 550W panels are high efficiency and will generate a substantial amount of power, especially in sunny conditions.
Cons: Ensure the panels are from a reputable brand with a good warranty (25 years is standard for performance).
Deye Inverter:
Pros: Deye inverters are known for their reliability and efficiency. The 8 kW capacity is suitable for off-grid applications, providing enough power for most small to medium-sized installations.
Cons: Confirm the specific model supports off-grid use, as some inverters are designed primarily for grid-tied systems. Deye does offer off-grid capable models, so make sure you’re getting one of those.
Battery:
Pros: A 10 kW battery will store a decent amount of energy, useful for evening and nighttime usage when solar panels are not producing power.
Cons: Verify the battery’s brand, cycle life, and warranty. Lithium-ion batteries are typically preferred for their longevity and efficiency.
Cost Evaluation:
The quoted price of $21,600 seems reasonable considering the capacity and components. However, installation costs can add a significant amount, so it’s essential to get quotes that include installation or get a separate installation quote.
Additional Considerations
Installation Costs: Since installation is not included, you should obtain quotes from local installers. Installation costs can vary but expect to add $5,000 to $10,000 depending on complexity.
System Design: Ensure the system design meets the energy needs of your sporting club. A professional assessment can help optimize the number of panels, inverter size, and battery capacity.
Permits and Approvals: Check local regulations and ensure all necessary permits and approvals are in place.
Deye Inverters for Off-Grid Use
Deye inverters are generally suitable for off-grid use, provided you have the correct model. They offer hybrid inverters that can work both on and off-grid, providing flexibility and reliability. Ensure the model you are quoted supports the following:
Off-grid functionality: Ability to operate independently of the grid.
Battery compatibility: Efficient integration with the battery storage system.
Load management: Proper handling of varying loads typical in a sporting club environment.
The quote you’ve received seems competitive for the equipment specified, but it’s crucial to:
Confirm the inverter model supports off-grid applications.
Verify the battery’s specifications and warranty.
Get a separate quote for installation.
Consider any additional costs for permits, approvals, and potential system upgrades.
By addressing these factors, you’ll ensure your local sporting club gets a reliable and efficient off-grid solar power system. Good luck with your project!
