How to Choose a Home Solar Power System: A Practical Guide Featuring SSTH Power
1. Why Choose SSTH Power?
Shenzhen ShengShi TianHe Electronic Technology Co., Ltd. (SSTH Power) is a China-based manufacturer specializing in power inverters, solar hybrid inverters, MPPT and PWM solar controllers, solar panels, and complete solar energy systems They offer a range of home-use solutions including:
- Hybrid solar inverters (off-grid, grid-tie, or dual-use) with pure sine wave output.
- MPPT controllers for high-efficiency solar charging.
- Complete off-grid solar kits, ranging from 2 kW to 10 kW capacity systems
2. Key Considerations When Choosing a Home Solar System
a. System Type: Off-Grid, Grid-Tie, or Hybrid?
- Off-Grid: Suitable where the electrical grid is unavailable or unreliable.
- Grid-Tie: Use solar power and feed excess back into the grid; ideal for reducing electricity bills.
- Hybrid: Combines solar, battery backup, and grid connectivity—maintains power during outages. SSTH Power provides hybrid inverters with MPPT control and pure sine wave output
b. Output Quality: Pure Sine Wave Inverter
Always opt for pure sine wave output—this ensures safe and stable power for modern electronics. SSTH produces inverters from about 3 kW up to 11 kW capacity, supporting parallel configurations for future scalability
c. Control Technology: MPPT vs PWM
MPPT controllers are significantly more efficient than PWM, especially under cloudy or variable lighting conditions. SSTH integrates MPPT tech into many of their hybrid inverters, enhancing performance
d. Monitoring & Connectivity
Modern inverters should include system monitoring. SSTH models offer communication interfaces like USB, RS232/RS485, Wi-Fi, and even GPRS options for remote monitoring and smart control
e. Battery Compatibility & Protection
Choose systems that support both lead-acid and lithium batteries, with multiple protective features (low/high voltage protection, overload, short-circuit safeguards). SSTH’s off-grid inverters come with these advanced protections and LCD/LED status displays
f. Certifications & Experience
SSTH holds certifications such as CE and RoHS, and demonstrates its presence in the industry via participation in global expos like CES and IFA
3. Practical Steps to Design Your Home Solar System
| Step |
Action |
| 1. |
Estimate Energy Usage – Calculate your peak power demand and daily electricity consumption. Aim for a system with about 20–30% expansion margin. |
| 2. |
Determine System Type – For resilience and flexibility, a hybrid system is often the best choice. |
| 3. |
Select an Appropriate Inverter – For most homes, a 5–11 kW pure sine wave hybrid inverter is suitable; SSTH offers models like 5.5 kW with MPPT and Wi-Fi/GPRS options |
| 4. |
Match Solar Panels & Battery Storage – Opt for high-efficiency monocrystalline panels and lithium batteries (LFP) for longevity and performance. |
| 5. |
Plan for Monitoring and Control – Integrate Wi-Fi or GPRS-enabled inverters for real-time performance tracking. |
| 6. |
Ensure After-Sales Support – Choose brands like SSTH with certifications, product diversity, and exhibition visibility. |
