The heat pump is 1kw. Yes the oven is daytime only

Building 100% off-grid farmhouse (Location Zinbabwe) — looking for real-world feedback Planned system: • 30 × 605 W panels (~18.15 kWp) • 3 × LuxPower SNA6000 in parallel (18 kW AC) • 2 × Hinaess PowerGem PLUS 51.2 V, 14.3 kWh each (28.6 kWh nominal) — provision for a 3rd Use strategy: run all heavy daytime loads (induction 2-plate, under-counter oven, washing machine, 1 HP borehole, 0.5 HP booster VSD, 300 L heat-pump) during sun hours only. Night loads limited to fridge, freezer, lights, TV, fans, brief booster runs. Important: I’m intentionally oversizing PV so daytime loads are covered by panels and batteries see minimal daytime cycling — I want these batteries to last as long as possible. Questions: 1. Is LuxPower + Hinaess a sensible, cost-effective choice here, or should I go Victron + [brand X batteries]? 2. Any real-world experience running heavy daytime loads off-grid like this? What practical pitfalls did you hit?
