In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by amending your registration statement and providing the requested information. If you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing any amendment to your registration statement and the information you provide in response to these comments, we may have additional comments. Unless we note otherwise, our references to prior comments are to comments in our January 27, 2023 letter. Form S-4/A filed February 14, 2023 General 1. We note your response to prior comment one, but disagree that Tigo Energy, Inc. ("Tigo") is not a "covered person" under Rule 14e-5. Accordingly, please provide your analysis on how the agreement for Tigo to purchase common stock and private placement units would comply with Rule 14e-5. 2. With a view toward disclosure, please tell us whether your sponsor is, is controlled by, or has substantial ties with a non-U.S. person. Please also tell us whether anyone or any entity associated with or otherwise involved in the transaction, is, is controlled by, or has substantial ties with a non-U.S. person. If so, also include risk factor disclosure that addresses how this fact could impact your ability to complete your initial business Gordon Roth FirstName LastNameGordon Roth CH Acquisition IV Co.

For instance, discuss the risk to investors that you may not be able to complete an initial business combination with a U.S. target company should the transaction be subject to review by a U.S. government entity, such as the Committee on Foreign Investment in the United States (CFIUS), or ultimately prohibited. Further, disclose that the time necessary for government review of the transaction or a decision to prohibit the transaction could prevent you from completing an initial business combination and require you to liquidate. Disclose the consequences of liquidation to investors, such as the losses of the investment opportunity in a target company, any price appreciation in the combined company, and the warrants, which would expire worthless. 3. We note the use of the term "fully diluted" throughout the registration statement, although the information presented does not reflect conversion of the convertible note or exercise of certain warrants. Please revise the term appropriately, or alternatively revise the information to reflect full dilution. Risk Factors There are risks to our public shareholders who are not affiliates of the Sponsors..., page 71 4. We note your response to prior comment 41 and re-issue it in part. Please revise your risk factor disclosure to include a cross-reference to the discussion of the various interests disclosed on pages 136-40, 220-22, and 288-92.

Please further revise your disclosure to include compensation information for your directors, in addition to your executive officers. ROCG Management's Discussion and Analysis of Financial Condition and Results of Operations Liquidity and Capital Resources, page 144 6. The disclosure on page 144 appears to indicate that ROCG issued a convertible note in an aggregate principal amount of $50 million on January 9, 2023; however, the disclosure on page 248 states Tigo issued a convertible note in an aggregate principal amount of $50 million on January 9, 2023. Please revise your disclosure to address this apparent discrepancy. The Business Combination Background of the Business Combination, page 200 7. We note your response to prior comment 23 that the references to forward purchase agreements (e.g., on pages 16 and 207) are to "transactions that would constitute capital raise transactions under the merger agreement and not transactions currently contemplated by ROCG." Please provide your analysis demonstrating how such agreements comply with Rule 14e-5. Gordon Roth Roth CH Acquisition IV Co. February 28, 2023 Page 3 Sponsors' Prior SPAC Experience, page 214 8.
