<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">On April 25, 2022, the Audit Committee
of the Board of Directors of Pioneer Power Solutions, Inc. (the &#8220;Company&#8221;) decided not
to renew the engagement of BDO USA LLP (&#8220;BDO&#8221;) and therefore has dismissed BDO as the Company&#8217;s independent registered
public accounting firm, effective immediately.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The reports of BDO on the Company&#8217;s
consolidated financial statements for the two most recent fiscal years, ended December 31, 2021 and December 31, 2020, did not contain
an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope, or accounting principles.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">During the two most recent
fiscal years, ended December 31, 2021 and December 31, 2020, and the subsequent interim period through April 25, 2022, there were no
disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) with
BDO on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which
disagreements, if not resolved to the satisfaction of BDO, would have caused BDO to make reference to the subject matter of the
disagreements in connection with its reports on the Company&#8217;s consolidated financial statements for such years. Also during
this time, there were no &#8220;reportable events,&#8221; as defined in Item 304(a)(1)(v) of Regulation S-K.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The Company provided BDO with
a copy of the above disclosures and requested that BDO furnish the Company with a letter addressed to the Securities and Exchange Commission
stating whether or not it agrees with the statements made above. A copy of BDO&#8217;s letter dated April 25, 2022 is attached as Exhibit
16.1 to this Current Report on Form 8-K.</p>
