★☆☆☆☆ — Serious Fulfillment Failure and Poor Customer Service We placed an order on Wednesday, May 7, 2026, with an expected delivery early the following week. The order was not shipped for two full days, and we received no tracking information or proactive communication about the delay. When I contacted customer service to understand the delay, representative Justin was dismissive and showed zero concern. When I asked why the order hadn't shipped on time, his exact response was: "It shipped out, what more do you want." No apology was offered, no explanation was given, and no effort was made to expedite or resolve the situation. The shipping delay will cause our project to miss its deadline, resulting in a contract default — a significant financial consequence for our business. Despite informing the rep of this, he remained indifferent. No refund, discount, or consolation of any kind was offered. We have been customers of this company for 20 years. That history meant nothing to the representative or, apparently, to the company. I would strongly caution any business that relies on timely delivery for project deadlines to look elsewhere. This company has demonstrated they do not value long-term customers or take accountability for fulfillment failures.

It took multiple phone calls and emails to have my order completed. I placed the order on 4/13/26. I kept checking the order status and all I ever saw was "processing". I finally contacted them on 4/21/26 and the person I spoke to seemed baffled as to why the order had not been shipped. She said she'd get back to me that day but didn't. I contacted her again the next day and finally the order was shipped. I think that somehow whoever was in charge of processing the order dropped the ball.

Had what I needed in stock and prompt shipping

BUYER BEWARE !! I purchased a $1550.00 inverter for a customer's motorhome. When I returned for the install, the inverter was different than the original. I had matched the model numbers and ordered accordingly, but 2 circuits were missing from the new inverter. So, I called and explained the wiring difference and was told I needed to purchase a 3kw model vs. the 2kw that was original. I explained that I did read the entire description and nowhere did it reference any wiring circuit specifics. I was told that information is from the manufacturer not Inverter Supply. I ordered the 3kw for $1964.00 immediately. The new inverter was not packed correctly, as per Inverter Supply's description. Just shipped in 1 box without packing materials surrounding it, no 2nd box. and it was damaged but worked fine. I packed the original new inverter in 2 boxes, completely surrounding with packing material. I called for return instructions I had not received yet and when printing them noticed a 20% restocking fee. THAT IS INSANE ! $310 plus I have to pay shipping and insurance. As a service business, I would never have spent another $2000.00 with a company that penalizes customers for spending more $$ with them. SO I AM OUT $1655.85 AT THIS TIME. BEWARE, IF YOU ORDER ANYTHING YOU WILL NOT RECEIVE A REASONABLE REFUND !!

I purchased a pallet of aptos 550w panels of their website for approximately $6400 and the sale was approved on my credit card. The next day their sales rep calls me and demanded that I pay an additional $700 because they were not able to make a profit. I told him that I had already made the purchase and that was ridiculous. He promptly told me he was canceling my order and hung up on me. Now my order shows cancelled out of stock, which is a lie. So they have no integrity and are unprofessional enough to post items for sale on their website and then try to increase the price AFTER the sale! Bait and Switch tactics and I have proof.

DO NOT BUY FROM THIS COMPANY!! Only 2 week return window AND it has a 35% restocking fee. They leave you high and dry with your expensive product. Literally purchase from anywhere bc this company is trash.

I bought an AP Systems ECU-R from Inverter Supply for $312 + tax on 04/09/2025. It was easy to order, delivered quickly, well packaged, and works.

Purchased a new 10kva inverter from Inverter Supply. Surprised it shipped in only in a cardboard box. We have purchased inverters from them before and always shipped in crates. When opened, the ears were damaged. This is 108 lbs. There is no way a cardboard box will protect it. To top it off, it was missing the mounting brackets. Calling customer service gave me excuses. First, she said it was shipped directly from Victron and was not their responsibility. Then, she finally admitted that the shipment originated from their warehouse since I had the shipper and tracking #. Inverter Supply's technical support is great, but the shipping department is poor. It looks like they took a returned unit and reshipped it without packaging. The root cause is that the product was not shipped in its original packaging and looks like a return.
