What would be the cost if install solar with battery for off-grid and not under NEM. Meaning using solely solar and only would tap into TNB if solar power not enuf.
Home solar 4 months in.

Is it possible to have solar <> battery <> grid? Meaning use solar exclusively and fall back to grid if charge is low. Would these NEM company entertain this request?

QUOTE(ameliorate @ Apr 29 2025, 04:26 PM) But why? I thought NEM is to compensate extra capacity. You put another battery wouldn't have much extra and the battery is not cheap too. So that when there is a blackout, I can still have electricity.QUOTE(ExpZero @ Apr 29 2025, 05:22 PM) Yes, they quote me extra RM20k++(For Huawei Luna 2000, the price is fair tho, it's market price) for battery and told me it's not worth it. If I insist, they will do it for me. which company? |

QUOTE(adamw @ May 4 2025, 08:56 PM) It's just that most vendor too busy with NEM on grid for them to do hybrid system, batteries are very affordable already. To do hybrid need keep hybrid inverter+battery stock and also more work needed for installation. So if it is under NEM, user can't have battery installed due to policy?Or is it can be used along with NEM as long as user willing to spend? |

Verdant just quoted me RM45.680 after RM11415 rebate) for 10.54 kWp Fox Hybrid + 6 kWh BESS.
Is this good deal? |

QUOTE(adamw @ Nov 30 2025, 02:06 PM) I presumed is single phase? Inverter 8kW? Panel is what spec? 6kwh battery looks miserable unless your TNB night time usage is very low. 3 phase. 6 kWh BESS x4 units. This post has been edited by nyunyu: Nov 30 2025, 02:46 PM |
