Buyer FAQ
ES Lite vs full 5000 ES—what changes?
Lite variants trade size/weight for similar power class. Send enclosure space and cooling—we will pick the SKU that fits your cabinet.
How many parallel units for a 15 kW site?
Typically three 5000 ES units if loads are balanced across phases—provide a load table for phase and surge review.
What should I include in an RFQ for a fast quote?
Destination market, model (3500 ES Lite / 5000 ES / 5000 ES Lite), PV array size and string voltage plan, battery type (48V LFP/lead-acid) and target kWh, plus generator input/transfer requirements.
