Job Overview
Job Title: Presale Engineer (Solar Energy)
Company: Growatt Energy
Job Type: Full-Time
Qualification Required: BA/BSc/HND
Location: Lagos, Nigeria
Job Field: Engineering / Technical
What Does a Presale Engineer Do?
A Presale Engineer sits at the intersection of technical engineering and commercial strategy. Rather than waiting until after a sale is closed, this role gets involved before the deal is signed — helping the sales team understand client needs, recommend the right solar configuration, and present a technically sound case that builds buyer confidence. In the context of Growatt’s solar and energy storage portfolio, this means working closely with distributors, installers, and end users across Lagos to translate technical specifications into solutions that actually solve real energy problems.
This is not a desk-only role. Expect a mix of office-based proposal work, client site visits, product demonstrations, and collaborative sessions with the regional sales and engineering teams.
Key Responsibilities
Evaluate client energy requirements and recommend suitable PV inverter, hybrid inverter, or energy storage configurations
Prepare technical proposals, system sizing documents, and cost estimates to support the sales process
Conduct product demonstrations and technical briefings for distributors, installers, and prospective clients
Support contract negotiations by clarifying technical capabilities, warranty terms, and installation requirements
Collaborate with the engineering and after-sales teams to ensure proposed solutions are installable and serviceable in real field conditions
Represent Growatt at trade exhibitions, distributor trainings, and customer forums across Lagos and neighboring regions
Gather market and competitor intelligence to inform product positioning and future solution design
Maintain accurate technical documentation for every proposal and client engagement
Provide pre-installation guidance to ensure smooth handover to the after-sales and installation teams
Requirements and Qualifications
A Bachelor’s degree, BSc, or HND in Electrical/Electronic Engineering, Renewable Energy, Physics, or a related technical discipline
Prior exposure to solar PV systems, inverters, or energy storage products is a strong advantage
Comfortable interpreting technical datasheets, wiring diagrams, and system schematics
Strong communication skills, with the ability to explain technical concepts to non-technical stakeholders
Willingness to travel locally for client visits, installations checks, and exhibitions
Proficiency with basic office and presentation tools (Excel, PowerPoint, or equivalent)
A proactive, problem-solving mindset suited to a fast-growing, client-facing technical environment
Skills That Will Help You Succeed
Beyond the formal qualifications, candidates who thrive in presale engineering roles typically bring a blend of curiosity and discipline. You should be comfortable asking clients probing questions to uncover their real energy needs, while also being detail-oriented enough to produce error-free technical quotations. Familiarity with Nigeria’s power landscape — grid instability, generator dependency, and the resulting appetite for solar-plus-storage systems — will give you an edge in understanding why customers are buying and what objections to expect.
Why Consider a Career at Growatt Energy
Joining a global renewable energy brand at a moment when Nigeria’s solar adoption is accelerating offers more than just a job — it offers a front-row seat to one of the country’s fastest-growing industries. Presale engineers gain exposure to international product lines, structured technical training, and a career path that can lead toward senior technical sales, product management, or regional engineering leadership. For engineering graduates who want their technical degree to translate into commercial impact rather than sitting behind a desk all day, this kind of hybrid role is hard to beat.
