Hebei Mutian Solar Energy Technology Development Co., Ltd. is one of the most reliable manufacturers and suppliers of complete 20kw hybrid grid system in China, also supports customized service. Welcome to buy advanced complete 20kw hybrid grid system in stock from our factory.
Why Choose Us as Your Hybrid System Partner?
You are not just buying a box – you are buying confidence. Here is what makes us different:
Complete Package, One Supplier
We deliver everything: panels, inverter, battery, cabinet, cables, breakers, and monitoring hub. No chasing three vendors for warranty claims.
Pre‑Configured to Your Local Grid
We set grid profiles (export limits, anti‑islanding, frequency‑watt response) before shipping. Your electrician simply connects and turns it on – no complex programming.
Transparent Pricing + Utility Paperwork Help
We provide a fixed, itemized quote. And where net metering or interconnection applications are required, we prepare all documents and single‑line diagrams for you.
Real References in Your Region
We will connect you with other 20kW hybrid owners near you – they will show you their systems and share actual savings.
Core Advantages – Why This Complete 20kw Hybrid Grid System Outperforms Others
Battery Cell Safety – The Foundation of Trust
We use LiFePO₄ (Lithium Iron Phosphate) chemistry – the safest lithium battery type for residential and commercial use. Unlike other chemistries, LiFePO₄ does not undergo thermal runaway. It tolerates high temperatures, resists overcharging, and will not catch fire even if punctured. Each cell is individually tested for internal resistance and capacity matching.
Intelligent BMS (Battery Management System) – Your Silent Guardian
Our 8‑stage BMS continuously monitors every cell's voltage, temperature, and current. It automatically:
Balances cells during charging
Disconnects loads before over-discharge damages the battery
Prevents over-current and short circuits
Logs all events for remote diagnosis
The BMS communicates with the hybrid inverter to ensure optimal charging algorithms – extending battery life by years.
Cycle Life That Pays Back for Decades
Rated for over 6,000 deep cycles at 80% depth of discharge. In real-world usage (daily partial cycling), the battery outlasts the panels. You will replace your roof before you replace this battery.
Modular Design – Start Small, Grow Big
The complete 20kw hybrid grid system is built from stackable battery modules. Need more storage in the future? Add 2–3 modules without changing the inverter or rewiring. Each module is hot‑swappable – no system shutdown during expansion.
Smart Monitoring – Full Control from Your Phone or Web
Real-time dashboard shows:
Solar production (today, this month, this year)
Battery state of charge and estimated runtime
Grid import/export (live and historical)
Carbon offset (visualized as trees planted)
Technical & Performance Description
| Category | Description |
|---|---|
| Battery capacity range | Sufficient to power a medium business or large home through 8–12 hours of no solar (overnight + cloudy morning) |
| Nominal voltage | High-voltage DC architecture – reduces cable losses and improves efficiency |
| Round-trip efficiency | >92% – you get back almost all the energy you store |
| Operating temperature | -20°C to 55°C. For extreme climates, an optional thermal management kit maintains performance |
| Ingress protection | Battery cabinet: IP65 (dust-tight and protected against low-pressure water jets). Inverter: IP54 (suitable for covered outdoor or garage installation) |
After‑Sales Service & Warranty
24/7 Technical Support – Real Engineers
Call, email, or WhatsApp. For critical failures (system down, no backup power), we escalate to an on‑call engineer within 2 hours. Most issues are resolved remotely via diagnostic access.
Regional Spare Parts Hubs
We stock control boards, battery modules, and fans in North America, Europe, and Australia. Standard delivery: 3–5 business days. Expedited: 24–48 hours.
Battery Trade‑In Program
When battery technology advances, return your old modules for a credit toward newer, higher‑density units. You keep the same inverter and cabinet – upgrading costs far less than a full replacement.
Annual Remote Health Check
Once a year, we pull your system's operational data and email you a simple report: "All good" or "We recommend a firmware update" – which we then help you install remotely.
