Frequently Asked Questions
Find answers to common questions about Haven Deer off-grid solar kits, LiFePO₄ batteries, all-in-one ESS, hybrid solar inverters, OEM & ODM services, and global order support.
How do I choose the right system for my region (US/EU/Africa)?
Since all Haven Deer systems are off‑grid – they charge from PV, the grid, or a generator, but never export to the grid – the payback logic is different from grid‑tied solar. Here are three real‑world scenarios that show how our solutions deliver a fast return, whatever your location.
Scenario 1 – Remote Farm / Off‑Grid Home (Replacing a Diesel Generator)
Typical for rural Europe, Africa, or Latin America.
Current cost: A diesel generator running 8 hours/day consumes ~10 litres/day – at €1.50/litre, that’s €15/day (≈€450/month).
Our solution: 6kW hybrid inverter + 10kWh LiFePO₄ battery + solar panels.
Result: Daytime solar + battery storage reduce generator runtime by 70% (generator only starts during extended cloudy periods).
Annual savings: €15/day × 70% × 365 days = ~€3,800/year.
Simple payback: System hardware ~€8,000–10,000 → ~2.5–3 years (plus you eliminate noise, fuel logistics, and frequent maintenance).
Scenario 2 – New Off‑Grid Home / Eco‑Lodge (Avoiding Costly Grid Extension)
Typical for remote sites in the US, Canada, or Australia.
Current cost: The local utility quotes €20,000–50,000 to run a new grid connection over 1 km.
Our solution: 10kW inverter + 30kWh battery bank + PV array – fully self‑sufficient.
Result: Zero electricity bills from day one.
Immediate advantage: Total system cost ~€15,000 – you save €5,000–35,000 upfront compared to paying for the grid extension, and you never pay a monthly utility bill.
Scenario 3 – Unstable Grid with Backup Charging (Grid‑Assisted Off‑Grid)
Typical for regions with frequent blackouts or voltage fluctuations (parts of Southeast Asia, Eastern Europe, Latin America).
Current cost: Grid electricity is available but unreliable, at ~€0.25/kWh. Monthly bill ~€150.
Our solution: 5kWh wall‑mounted battery + hybrid inverter, with the grid connected as a backup charger (no feed‑in). Solar covers daytime loads, battery discharges at night, and the grid only kicks in during prolonged bad weather.
Result: Grid purchases drop by 60–80% – new monthly bill ~€40.
Annual savings: (€150 – €40) × 12 = ~€1,320/year.
Simple payback: System cost ~€4,000 → ~3 years, and you eliminate all power‑outage downtime.

Can different Haven Deer products be used together?
Yes. Our products are designed to work together in complete off-grid solar energy storage systems. Hybrid solar inverters, LiFePO₄ batteries, and complete solar kits can be configured according to different project requirements.
Do you support OEM and ODM projects?
Yes. We provide OEM and ODM services, including private labeling, customized product configurations, packaging design, and branding support for distributors, installers, and energy solution providers.
Which international certifications do your products have?
Depending on the product model, our solutions support international certifications and documentation including CE, UN38.3, MSDS, and compliance with applicable IEC standards. Please contact us for model-specific certification details.
Do you ship products worldwide?
Yes. We support global shipping and work with customers across different regions. Our team can recommend suitable shipping solutions based on product type, destination, and order quantity.
How can I select the right solar energy storage solution?
Our technical team can recommend suitable product combinations based on your power requirements, installation environment, application scenario, and project goals. Contact us for personalized product recommendations.
Can I parallel connect different capacity LiFePO₄ batteries from Haven Deer?
Yes, but strictly via our BMS communication protocol. For example, you can parallel a 5kWh wall-mounted unit with a 15kWh portable unit, but you must set the master-slave dip switches correctly as per our manual. We provide the CAN/RS485 protocol codes upon request.
What is the peak efficiency of your 6kW inverter at 48V?
Peak efficiency is 94% at 40%–60% load. The MPPT range is 90V–280V, which is optimized for PV strings, reducing cable loss on long rooftop runs.
Do you offer white-label shipping with local EU/US plug types?
Tailored to your needs. We ship with Schuko, UK, Australian, and NEMA 5-15P plugs. We pre-configure the inverter output frequency to 50Hz/60Hz based on the final destination during ODM production.
