* Revenue for the first quarter of 2020 of $205.5 million included approximately $44.5 million of safe harbor revenue.
Total revenue increased 14% compared to the fourth quarter of 2020 as we continued to experience strong worldwide demand for our solar and storage systems. We reported record quarterly revenue in the U.S., Europe, and Australia, despite normal seasonality in the first quarter. Our operations team did an excellent job of navigating component supply constraints to best service our customer demand, while improving inventory in the channel.
Our non-GAAP gross margin increased to 41.1% in the first quarter of 2021, from 40.2% in the fourth quarter of 2020, driven by disciplined pricing and cost management. Non-GAAP operating expenses increased to $43.7 million in the first quarter of 2021, compared to $34.2 million in the prior quarter, primarily due to increased investments in research and development, increased hiring, payroll tax associated with employee stock vesting, and the consolidation of Sofdesk operations in late January. Non-GAAP operating income was $80.2 million, compared to $72.4 million in the prior quarter.
We exited the first quarter of 2021 with $1,489.0 million in cash and generated $75.8 million in cash flow from operations. The cash balance includes net proceeds of approximately $1,189.4 million from the convertible notes issuance in March 2021 and is partially offset by $304.8 million paid in principal amounts for the partial repurchase and conversions of the convertible notes due 2024 and 2025. Inventory was $34.9 million at the end of the first quarter of 2021, compared to $41.8 million at the end of the fourth quarter of 2020. The sequential decrease in our inventory was driven by an increase in customer demand coupled with supply constraints.
We made good progress on the rollout of our Enphase Storage systems by reducing commissioning times. We introduced 24/7 global customer support and are pleased to resume in-person installer training, while also continuing our online certification. In addition, we recently expanded our Enphase Installer Network (EIN) in the Netherlands and Belgium, after successful launches in the U.S. and Australia. Our EIN installers can enjoy a variety of tools and services on Enphase’s digital platform to help make the sales and installation process faster and easier, while providing an exceptional experience to homeowners across the globe.

(1) We sought refunds totaling approximately $38.9 million plus $0.6 million accrued interest on tariffs previously paid from September 24, 2018 to March 31, 2020 for certain microinverters that qualify for the tariff exclusion on Chinese imported microinverter products that fit the dimensions and weight limits within a Section 301 Tariff exclusion under U.S. note 20(ss)(40) to subchapter III of chapter 99 of the Harmonized Tariff Schedule of the United States. The refund request was subject to review and approval by the U.S. Customs and Border Protection; therefore, we assessed the probable loss recovery in the three months ended December 31, 2020 was equal to the $16.5 million approved refund requests available to us. For the three months ended December 31, 2020, we have recorded $15.9 million as a reduction to cost of revenues and $0.6 million as interest income in our consolidated statements of operations as the approved refunds relate to paid tariffs previously recorded to cost of revenues. No tariff refunds were recorded as a reduction to cost of revenues in the three months ended March 31, 2021 and 2020.
(2) Loss on partial settlement of convertible notes of $56.4 million for the three months ended March 31, 2021 primarily relates to the $9.5 million non-cash loss on partial settlement of $87.1 million aggregate principal amount of the Notes due 2024, $9.4 million non-cash loss on partial settlement of $217.7 million aggregate principal amount of the Notes due 2025 and $37.5 million non-cash inducement loss incurred on repurchase of Notes due 2025. Loss on partial settlement of convertible notes of $3.0 million for the three months ended December 31, 2020 is related to partial settlement of $43.9 million aggregate principal amount of the Notes due 2024.
(3) Change in fair value of derivatives of $15.3 million for the three months ended March 31, 2020 represents changes in fair value of the conversion option in the Notes due 2025, as well as the convertible note hedge and warrant transactions. Initially, conversion of the Notes due 2025 would be settled solely in cash as a result of the Company not having the necessary number of authorized but unissued shares of its common stock available to settle the conversion option of the Notes due 2025 in shares; therefore, the conversion option, convertible note hedge and warrant transactions were classified as derivatives that required marked-to-market accounting. On May 20, 2020, at the Company’s annual meeting of stockholders, the stockholders approved an amendment to its certificate of incorporation to increase the number of authorized shares of the Company’s common stock. As a result, the Company is now able to settle the Notes due 2025, convertible notes hedge and warrants through payment or delivery, as the case may be, of cash, shares of its common stock or a combination thereof, at the Company’s election. Accordingly, on May 20, 2020, the conversion option, convertible note hedge and warrant transactions were remeasured at fair value and were then reclassified to additional paid-in-capital in the condensed consolidated balance sheet in the second quarter of 2020 and are no longer remeasured as long as they continue to meet the conditions for equity classification.
