Start with what the customer actually needs
You want clear steps, not long theory — this is for dealers who meet facility managers, EPCs, and finance people. Begin by asking site-first questions: load profile, backup requirements, grid export rules, and CAPEX vs OPEX preference. If you already talk with battery energy storage system manufacturers and compare notes with bess oems, your proposals will match reality faster. I’ve seen the same blind spots at trade stands and technical talks, even at Intersolar Europe, so start practical.
Qualify leads the user-centric way
Dealers must filter prospects early. Ask direct, measurable questions and score them. Keep it simple:- What problem do you solve: peak shaving, demand charge reduction, resiliency, or energy trading?- What is the average daily kWh and the largest single-hour load?- Do you need islanding capability or only grid-following?- Budget range and decision timeline (months, not “soon”).Use a 1–5 score per answer. Anything below 2 for timeline or budget is low priority. You save time and build trust by being clear, lah.
Match technology to need — concrete checks
Not every project needs high-power inverters or extreme cycle-life chemistry. Check these technical fit points:- Round-trip efficiency target (≥88% for commercial sites).- Depth of discharge and cycle-life expectations (match chemistry: LFP vs NMC).- Inverter compatibility and communication protocol (Modbus, SunSpec).- Site thermal management and container vs indoor rack options.Quote performance numbers, not marketing lines. Clients respond to specs and expected lifecycle cost.
Proposal and commercial terms that close deals
Make proposals easy to compare. Include clear outputs:- Energy and demand savings modeled yearly.- Simple payback and IRR ranges with conservative assumptions.- Warranty scope: cell, BMS, inverter, and workmanship — state years and capacity retention.- Service model: response time, spare parts, who owns commissioning.Avoid vague promises; put milestones and acceptance tests into the contract.
Common procurement pitfalls and how to dodge them
Dealers trip over repeatable issues. Watch out for:- Mismatched commissioning responsibility (OEM vs dealer vs EPC).- Missing site power studies — protection settings can block energisation.- Logistic gaps: transport, lifting plan, and HVAC for containerised units.- Failure to include cyber-security and telemetry scope.Prevent delays by defining roles in SOW and by confirming local permits early.
Practical commissioning checklist
Commissioning must prove performance. Use this checklist during site acceptance:- Verification of mechanical installation and grounding.- BMS/Battery health check and factory firmware confirmation.- Grid interconnection tests: anti-islanding, protection relay coordination.- Functional tests for each operating mode: charge, discharge, islanding.- Final handover: O&M manual, as-built drawings, telemetry credentials, and training for local staff.Document each test with time-stamped logs and photos. That record protects both dealer and customer.
Service, monitoring, and long-term relationship
After handover, revenue and reputation depend on follow-up. Offer monitoring with alert thresholds and monthly performance summaries for the first year. Train the customer on normal alarms and a single escalation path for support. Transparent reporting keeps expectations aligned and reduces churn.
Common mistakes new dealers make
Be honest: new dealers oversell capability, under-document, or ignore small details that shut down acceptance tests. Fix it by:- Using standard acceptance test templates.- Including staging and FAT language in purchase orders.- Running a mock handover with the customer before final commissioning.Small process items save expensive rework later.
Wrap-up and practical next step
Keep the customer at the center: score leads quickly, match specs to real needs, make proposals with measurable outcomes, and treat commissioning as the visible finish line. These practices come from hands-on project cycles and repeated field lessons. When systems must integrate smoothly with existing operations, experience matters — so align your process to providers that document performance and support responsibly like Dunext.
