ChargeWise Systems is an independent multi-brand specialist retailer founded in 2019. We are a team of electrical engineers and certified renewable energy installers who focus exclusively on power inverters, battery chargers, and related conversion equipment. We are not the official store for any brand, but we are authorized to sell products from the brands we carry.

We specialize in DC-AC inverters, battery monitors, solar charge controllers, and power accessories. Our catalog includes products from Victron Energy and Cobra, selected for their real-world performance and reliability. We provide detailed technical guidance to help you choose the right solution for your application.

We choose products based on performance, build quality, safety certifications, and long-term reliability. We test key models, compare them against others in the category, and only list items we are confident will meet our customers' needs. Our team's technical background ensures we carry only the best in class.

We are an independent retailer with low overhead compared to big-box stores. We buy from authorized North American distributors and leverage quantity discounts on fast-moving models. For slower-moving variants, we keep inventory lean to reduce storage costs. This allows us to price more aggressively while maintaining the same quality.

Discounts are funded from our operating margin, not from supplier incentives that could bias our recommendations. The depth of discount depends on the product's margin, demand, and current distributor pricing. We offer genuine savings on products we would carry anyway, and the amount can vary based on these factors.

We run promotions like SAVE15 from our regular margin. This means you get a real discount on eligible items, and it doesn't affect the quality or authenticity of the product. The code is applied at checkout, and eligibility follows the checkout rules.

We source all stock from authorized North American distributors that we vet and monitor. Before listing, we verify part numbers, specifications, and package contents against manufacturer reference data. Each unit carries a valid manufacturer warranty and full traceability. If you ever suspect an item is not genuine, we will replace it and cover return shipping.

If you have a concern, contact us with your order number, product serial number, photos, and a description. Our quality team reviews the photos and may request a return for physical inspection. We resolve within the promised timeline and follow up to confirm your satisfaction. If authenticity cannot be confirmed, you can choose a full refund or a replacement, plus a $50 account credit.

At our warehouse, each unit is visually inspected for packaging damage and tampering. For high-value inverters, we run a functional bench test before dispatch. We also review listings to prevent misleading errors. When your order arrives, check the outer box and contents against the packing list, and contact us if anything seems wrong.

We offer free shipping on orders over $45.00. For orders below that amount, standard shipping is $8.00. We ship from our Austin, TX warehouse, and provide tracking for all orders.

Once your order ships, you'll receive a tracking number via email. You can also contact our shipping support at shipping@chargewise.shop if you need assistance.

We accept returns within 30 days of delivery. If you need to return an item, contact us with your order number and reason for return. We'll provide instructions and a prepaid return label if applicable.

Refunds are issued to the original payment method after we receive and inspect the returned item. If there's an issue with the product, we may offer a replacement instead. We'll process your refund within a reasonable time after approval.

Warranty terms follow the product information and support guidance provided by the manufacturer. All products we sell carry a valid manufacturer warranty. For warranty claims, contact our after-sales team for assistance.
