新能源外贸打样、开模与技术确认话术

Hi {Name}, Load data received — thanks for the detail. Here's my proposed sizing (with the math shown so you can validate independently): **Your inputs**: - Daily load: 45 kWh - Peak load: 12 kW (10 min max) - Backup requirement: 12 hrs (winter cloudy day scenario) - Location: Bavaria (~1,150 kWh/kWp/year solar yield) - Grid: 3-phase 400V, feed-in allowed **Recommended system**: | Component | Spec | Qty | Rationale | |---|---|---|---| | PV modules | 550W mono TOPCon | 22 pcs (12.1 kWp) | Sized to cover annual load + 15% margin for EV growth | | Hybrid inverter | 12 kW 3-phase | 1 unit | Matches peak load + surge headroom | | BESS | 20 kWh LFP wall-mount | 1 unit | Covers evening/backup load, 2 kWh reserved for cold-cycle margin | | EMS | Included | | Time-of-use optimization + peak shaving | **Performance model** (typical year): - Solar production: 13,900 kWh/year - Self-consumption ratio: 74% (with BESS) vs 32% (without) - Grid feed-in: 3,600 kWh/year - Payback: 7.2 years at current EE feed-in tariff + retail rate **Total system price**: €14,200 EXW, includes 12-yr onsite warranty + monitoring app + commissioning support If any input is off (e.g. actual peak is 8 kW not 12), the system downsizes and price drops ~15%. Want to review the numbers on a 30-min call? Also happy to share the full performance simulation PDF. Best, {Your Name}

{名字} 您好， 负载数据已收，感谢详细数据。推荐配置（附计算逻辑供您独立验证）： **您的输入**： - 日耗：45 kWh - 峰值：12 kW（最长 10 分钟） - 备电需求：12 小时（冬季阴天场景） - 地点：巴伐利亚（约 1150 kWh/kWp/年发电量） - 电网：3 相 400V，允许上网 **推荐系统**： | 组件 | 规格 | 数量 | 理由 | |---|---|---|---| | 光伏组件 | 550W 单晶 TOPCon | 22 片（12.1 kWp） | 覆盖年负载 + 15% 电动车增长冗余 | | 混合逆变器 | 12 kW 3 相 | 1 台 | 匹配峰值 + 浪涌余量 | | 户储 | 20 kWh LFP 壁挂 | 1 台 | 覆盖晚间/备电，保留 2 kWh 冷循环余量 | | EMS | 含 | | 分时优化 + 削峰填谷 | **典型年性能模型**： - 光伏发电：13900 kWh/年 - 自用率：含储 74% vs. 无储 32% - 上网电量：3600 kWh/年 - 回本周期：7.2 年（按当前德东上网电价+零售电价） **系统总价**：€14200 EXW，含 12 年上门保修+监控 App+调试支持 如输入有偏差（如实际峰值 8 kW 非 12），系统降配价格降约 15%。方便约 30 分钟视频过一遍数字吗？也可发完整性能仿真 PDF。

Hi {Name}, Sample unit shipped — DHL AWB 88776655, ETA {date}. Serial number: BM5-260728-001. **Included in the box**: - 1× 5 kWh BESS unit (serial 001) - 1× hybrid inverter (serial IV-001, paired) - Wall bracket + all cables + terminations - Wi-Fi dongle (pre-registered to your account, credentials sent separately) - **Complete test report** — see below **Pre-shipment test results** (each unit tested, not batch): | Test | Result | Standard | |---|---|---| | Capacity | 5.08 kWh @ 0.5C, 25°C | ≥ 5.00 kWh | | DC internal resistance | 42.3 mΩ | ≤ 50 mΩ | | Charge/discharge efficiency | 96.4% round-trip | ≥ 95% | | Cell voltage delta | 8 mV max | ≤ 30 mV | | BMS protection: OV, UV, OT, SC | All triggered per spec | Per IEC 62619 | | Hi-pot 2500 V | Pass | UL 1973 | | Insulation resistance | 200 MΩ | ≥ 100 MΩ | | Communication (CAN + Wi-Fi + Modbus TCP) | All pass | | **What to test on your side**: 1. Full charge + discharge cycle end-to-end 2. Grid-tie with your local grid — check power quality (THD, PF) 3. Backup mode transition time (should be <20 ms UPS-grade) 4. Wi-Fi app functions on your local network 5. Load rejection / recovery per your grid code Suggest we book a 30-min video call 5–7 days after arrival — I can walk your engineer through anything unexpected. Bulk production stays on hold until your sign-off. Best, {Your Name}
